Except your "logical conclusion" missed the most important part of their comment. Here, let me fix it for you:

That all expressions of sexual desire ("between two consenting adults") are expressions of love, that all expressions of love are equally valid, and that no expression of love should be repressed.

I agree with this statement, and I think most people would. You're right as well that almost no one would agree with your thought experiment, as it opens up the argument that rape and sexual assault are "expressions of love" when they very much are not. I don't think that was an accident on your part though, considering your account is less than a day old and you decided to come straight to an lgbtq community and participate in the manner in which you have.

Oh no, I guess I'm a hedonist ¯\_(ツ)_/¯
