As long as Uncharted 5 doesn't feature a transsexual Nathan Drake, I'm good... Then it would smack of political agenda. Now it just seems like a part of ND's valuing of diversity, which is something Druckman has talked a lot about. I'm fine with that. I dislike SJW/feminist/leftist identity politics, but that's not what this seems like to me.
How would have gamers reacted if Joel was the gay one, rather than Ellie? I'm guessing the reaction would be very different. Most people find two women kissing to be interesting, not objectionable. But most gamers are guys, and I suspect a lot of them would have issues if the primary male protagonist was gay.
Val, I don't think you need to worry about explaining the reasons for your feelings, if that's what you want to do. You've made a couple of comments to the effect that if you were to go into detail, you'd get banned. Afaik, we've never banned anyone for politically incorrect opinions. This isn't GAF or Era, where you're going to be banned because you are "rationalizing hate speech" or whatever SJW terminology they are using this week. I think everyone knows where your position is coming from anyhow (your religious beliefs). You can expect ridicule, criticism, and push-back, but I don't think you need to worry about banning, unless you start trolling or making personal attacks on individual members.
