Absolutely you can be gay and Christian
You are one or the other, not both. Love the sinner, hate the sin has no meaning for a “gay” person because the ARE the sin. There is no separation.
Now the next question to the “gay” is to ask is it a sin.
There is a big difference between being gay and Christian vs being a sinner and Christian. I will let the reader think about that.........................
Did you read the rest of my post?
It would be no different than someone claiming that they were a Christian adulterer, a Christian extortionist, a Christian thief, a Christian murderer, and so on.
You cannot embrace your sin to the point of identity and use Christ as fire insurance.
