There are consequences to all actions, good or bad. Yes, you may strain your relationship with your significant other if you look at porn. However, it may not, and for all I know you and your significant other are busy fapping to it right now. Good for you! I trust that you can responsibly take care of your own life and I won't have to get into it.
If you like Hustler or Playboy, fine with me. I know, I know, a feminist defending perhaps two of the most misogynistic magazines ever. I'm fine with porn as long as I'm not looking at it, the models are paid, 21 and over, doing it without pressure, and giving full consent along with being fully comfortable with it. Because that's their damn business, not mine.
If you choose to sleep with other people, use protection, go to strip clubs, get a call girl or rent boy, that's your business. Leave me out of it and keep proper consent, pay your hourly $190, and after that, it's fine by me.
If you need an abortion, that's your own fucking business.
If I were to try to get into your life and fuck with it because of my morality, well fuck me. I shouldn't do that, neither should anyone else. Your morality is your own morality, so keep it to yourself and don't force it on everyone else. If I find something morally wrong in my religion and wish to ban it even though other people are of different religions than me, that is oppression. I am being Big Brother, which is exactly what these people are doing. They're just too ignorant to understand me because they throw around big words without looking at the context. Now excuse me while I live my personal, private life that involve things that offend many Christians.
