Go ahead, call me a reactionary after seeing all of the below (even though I'm pro gun control, pro-environment, pro-Palestine and anti-censorship) but given the illusion of knowledge I've learnt that people don't make judgements based on reason, just self interest so you shouldn't care much what they think.
I hate this anime on a number of levels; it's boring, it gives the misandrists more ammunition (as if we men weren't adept at screwing up our own already awful reputation as it is) and one of the worst anime I've ever seen is directed by the director of one of the best anime I've ever seen; the director of Serial Experiments Lain Ryutaro Nakamura. I seriously can't figure out how the same person was able to direct 2 anime so different in length, quality and focus. Right from the theme song things start going wrong; for some reason the girl is singing about being excited but in an angry voice and then along with the slightly crap animation we get to endure the actually not arousing exploits of the pitiful perverts who inhabit this waste of time, money and effort made all the worse by the fact that it's so short that the only facets of the characters' personalities are either they're perverted or they're the targets of the perversion, nothing more. The only males in this show just spend all of their time getting aroused looking at the women and in spite of cassieshhepgirl's review saying that Colorful is misogynistic but anime as a whole is I for one think it's not doing us males any favour either. There's already this stereotype in the west that all men are perverted barbarians because a test was done on rats that showed that when given testosterone that they were hornier and more aggressive and even though a rat and a human aren't the same thing it was convinient for the misogynists to assume that this automatically meant that men were all perverted jerks and unfortunately we're not doing much to combat this idea but I've seen porn (I'm not proud of it though) and the women make far more noise than the men so if anybody is in to sex it's women. What I've found is that men beat you up but women break you down emotionally and if you're going to get left in a bad state by someone it shouldn't matter in which way they do it. Physical wounds can hurt one's pride but psychological wounds can cause a person to harm themselves. Before there was pressure on women to be chaste and obedient back when women were seen as inferior the results being women didn't have much freedom now that if anyone is seen as inferior it's men it's strong and sexy the result being ballooning STD rates and women trying to be strong but trying too hard and ending up being jerks. One set of pressures was replaced with another so things are still bad but in different ways, much like life as a whole really. We've got such a sexualised society that the women's movement has become almost entirely focused on "women's health" (people not being able to realise that the whole purpose of gender is reproduction so they'll bang anything in sight at any time in any manner) and saying that sex is about control, yes they genuinely think that lots of men would be sick enough to rape someone for control when they could just tie them up and it wouldn't be over in minutes and that any man can be a rapist even though it;s usually someone you know and in today's cock worshipping of women it's somehow considered funny if a man gets raped by a woman because apparently women can't use weapons as well. Because of hedonism people insist that abstinence doesn't work because that's when teenagers are at their horniest even though since that's when you're most likely to catch an STD (the vaginal walls haven't fully thickened at that point) and are least able to support a kid so it's by far the best time of all to practice abstinence but since when has a basic knowledge of science trimuphed over fun for the sake of fun regardless of how short it lasts? Get pregnant, they judge you, never have sex, they call you a "loser", you can't win. Condoms may indeed be 97 or whatever % effective but people are having more and more sex younger and younger plus if you're drunk or high as people increasingly are you mightn't use one anyway so STD rates just keep multiplying. Condoms should remain legal, sure, but I fail to see how 97% safe is a better option than 99% (you might get an STD even if you've never had sex by coming into contact with pubic lice) and in any case sex involves where somebody goes to the toilet one way or another, even getting past the aesthetics of course there are going to be nasty diseases around and AIDS is incurable and fatal. Rare certainly but 100% awful and 100 is of course higher than 97 and given that people have lied about not having AIDS given all of the above I'll pass even on starting a family.
