I agree with the moderator that those comments were transphobic. The author seem to say one can "cure"/treat being trans by changing habits. This reminds me of those gay conversion camps, which at least where I live, is considered very homophobic.
The first few levels are really easy but after a while it gets more fun and challenging. I suggest looking doing "View solutions" after you've finished a level as well, some interesting things there sometimes, I learned a thing or to.
The closer comparison one can make the better, right?
Drinking coca cola isn't illegal or even looked down upon. Rape porn isn't advertisement for rape and is not meant to encourage people to rape. Coca cola advertisement/product placements is designed to make people buy it more.
The two cases are in my opinion very different.
Do you suggest rape porn or rape scenes in movies promote more rape in the real world? What about violence in video games? I don't claim to know the answer, but I've thought that was disproved (though I haven't really looked into it).
I think a more relevant question would be something like: Does watching rape porn make people more likely to rape? Does watching porn make people more or less likely to rape? Or something similar to that.
I'm sure there are places where porn has been illegal but later become legal, looking at how it changed the rape statistics might give some weak evidence (though correlation is not the same as causation of course).
Have you looked into Effective Altruism, The life you can save foundation, and/or GiveWell? They are all initiatives to make sure resources are used as effectively as possible when it comes to doing good.
