Christians and Homophobia

No hate to anyone here, I just want to ask a genuine question and I want to hear your honest opinions/answer about it.

So, As a christian myself I never understood with the massive homophobia in the christian community. Can a gay dude be Christian?
Most people might answer it as "No, because that would mean you're sinning" but aren't we always sining? For example, Me on this site LoL
There's nobody in this world who's actually an "angel" or "hasn't sin" and I think people are always exaggerating it when it comes to Lgbtq. So, Can gay people be Christian?

Also ye dont give me that "ask reddit" crap. If i wanted to do that, I would already.
