How would you respond IN A LOVING WAY to these anti-gay comments from LDS guy on YouTube

This is a comment under the new Linda Barney Mormon Stories episode (https://youtu.be/-uzFYWdkWEI):

> I will say this...being a part of the alphabet squad is a sin. It is black and white and no gray areas (read your scriptures). There are two biological units that God created...a man and a woman. Anything else is an abomination to the Lord. Does that mean the feelings are not supposed to be there? No, I have a friend that was raised in the church but his sexual orientation and desires are that of being gay. He struggles with it, but understands how the Lord feels about it, so he suppresses his feelings. I commend him for this as he lives in a world that says it's ok. It is not. I'm sure many will buck at this response, but God is the same yesterday, today and forever. Just because the world now accepts it as it is being jammed down our throats at every turn, doesn't make it right. and it doesn't make it ok for a Christian.

Someone responds with:

> So if god made them and they are gay why isn’t that good enough??m

And he responds with:

> Tell me that you personally don't have desires and passions you keep in check. We all have things in our lives that we need to suppress. We all have free agency and can do as we want, however, there are things we Don't do if we choose to return to Heavenly Father.

I used raised to believe this as well and slowly had my mind changed. But I still don’t know how to explain to someone like this (“in universe”) why this thinking about homosexuality as a sin is wrong. How would you respond if this was a family member that you loved?

AND PLEASE DON’T BRIGADE THIS GUY. He’s just ignorant, as many of us once were.
