"Optional" is a weasel word to incorporate degenerate shit into games in a deceitful way.

It's a huge investment to plan, engineer, script, voice-act, model, animate, implement, QA, even a single scripted narrative sequence in a game like this. It's a lot of work, it costs real money to pay all the people involved across multiple different disciplines. Therefore we must conclude that someone cared a lot about including faggotry in the game.

Just imagine someone made a "R4p3" mod for Sims, giving Sims the option to jump on other Sims and act that out. We would assume that person is a disgusting weirdo, even if it was entirely "optional." And we'd be right to assume that, because it's clearly true.
