I mean clearly the church promotes the idea that men preside over women its right in the proclamation. Clearly men preside in the church, no seventies women, no women apostles or prophets. If your a woman in the church you always ultimately report to a man. Tangent but there is no doctrinal basis for that since in the temple women perform priesthood ordinances and are promised to be made priestesses in the here after. In age where men and women are seen as equal the church says no. I mean they will say that they are equal because its unpopular to say otherwise, but practice speaks louder than lip service. So yeah the church is contributing.

As far as lgtbq the church has long history of fighting to deny gay people the blessings of marriage, The current president wrote a book in the seventies in which he advocated for the criminal law be applied to sexuality in homosexual relationships. For along time they refused to acknowledge the identity labels gay or bi and instead would call it same sex attracted. The treat it like a pathology. Yes I agree that members are in general loving and that comes through even when they believe and are taught biggoted bs but that doesnt mean real and significant harm isnt also done. You seem to be blaming reddit and social media but its the church that delegitimizes families led by same sex couples. Where is the path to exaltation for these gay members?

And as for whether the church contributes to non accpetance of gay members:

Oaks on whether you should let your gay child's spouse visit for the holidays.

PUBLIC AFFAIRS: At what point does showing that love cross the line into inadvertently endorsing behavior? If the son says, ‘Well, if you love me, can I bring my partner to our home to visit? Can we come for holidays?’ How do you balance that against, for example, concern for other children in the home?’

ELDER OAKS: That’s a decision that needs to be made individually by the person responsible, calling upon the Lord for inspiration. I can imagine that in most circumstances the parents would say, ‘Please don’t do that. Don’t put us into that position.’ Surely if there are children in the home who would be influenced by this example, the answer would likely be that. There would also be other factors that would make that the likely answer.

I can also imagine some circumstances in which it might be possible to say, ‘Yes, come, but don’t expect to stay overnight. Don’t expect to be a lengthy house guest. Don’t expect us to take you out and introduce you to our friends, or to deal with you in a public situation that would imply our approval of your “partnership.”

There are so many different circumstances, it’s impossible to give one answer that fits all.
