I'm not going to say that the Bible condones homosexual activity. Because it doesn't. Scripture says what it says, and if I'm dissonance in the Echo Chamber, so be it.
In 20-30 years, when your denomination sanctions gay marriage and even your particular church building performs them, you'll find some contrivance for how you were never actually wrong and the church isn't now either. Maybe a long string of paragraphs about how Muslims were always worse to the gays or something.
I know very little about Pentecostals, so I have no idea if there is a powerful pro-LGBT movement within that denomination. However, I have little doubt that in 20-30 years Bible believing Christians will be very unpopular. Anyone who still identifies as such won't care about social pressure at that point I think.
What is it with homophobes and thinking that the only reason we want them to change is "social pressure"? It's because accepting LGBT people is the morally right thing to do, not because it's hip or trendy.
Being opposed to interracial marriage and relationships does not make people racists. A lot of this civil rights movement has to do with social pressure. It's not even known how many people ACTUALLY support interracial marriage. Many of the polls from various research centers show interracial marriage support around 68%. I do not believe that support is that high. I think many of those opposed to interracial marriage are afraid to share their beliefs due to the hostile political environment we live in today. There is lots of hostility towards those who oppose interracial marriage. I have even received death threats. You all think that I am the intolerant one. Why do you care if somebody opposes interracial marriage? It's not your business! How does it effect you in anyway?
Edited your post for educational purposes. (And the irony of the last three sentences is epic.)
