Ok there's really nothing I can add to that last part which gamer hasn't covered except for one thing and that's Pornography.

I look at porn like this, is it harming anyone? No.
-> Note: I mean actually harming, not offensive in situations like "You watching Porn offends me".

Porn is also simply appeals to sexual drives/hormones which we as a human species evolved to have.
There is nothing wrong in taking pleasure in one of the main things that makes us human and alive.

There isn't any bad effects to porn (Except obsession, but this applies to anything that exists), and I don't count any thing like "It puts ______ in weak/lack of power position" or anything like that. It's Porn, there's many kinds of it that's meant to appeal to peoples kinks and interests. If anything, porn's helped people be smarter/wiser about their sex lives cause it acted as a way to fill their curiosity, release their sex urges and in cases where Sex Ed is lacking, somewhat educate themselves on the topic.

And note this is all coming from someone who has never bothered to watch porn growing up cause I never found much reason to personally. So I'm not even going at this from a "Don't you touch my porn!" perspective. :P
