I think we can be misled, perhaps, and I need to be aware not to contribute to this. I do think it's important to have compassion on those affected by this particular cross. HOWEVER ... such compassion cannot extend - ever - to saying that sin is not really sin. It is not the unforgivable sin, and I don't like to see people draw themselves up in self-righteousness, making special condemnation of those so tempted, just because they themselves are not tempted.
But no, it is and always has been sin. The Church has not and should not ever perform same-sex marriages. Individuals may develop different sympathies and opinions, but the teaching of the Church does not and should not change.
There have also been rather public voices in Orthodoxy of late that have tread close to this error, and that may be influencing public opinion. And FB is rather notorious for being one of the worst places for "internet Orthodoxy".
I don't mean to totally discredit FB, because I have a carefully developed list of friends there that are VERY edifying (with a few requests I also accepted that I have to be more careful of, but I know who they are in general at least). But FB Orthodoxy groups can be toxic (including some I'm probably a member of since I end up being added to everything). Be very careful there. And I hope you can be encouraged.
BTW, it IS important to understand that the Church is composed of people, many of whom are dealing with brokenness in varying degrees. They/we need the Church too.
But don't let individual people who might not have progressed in cooperating with grace of God to a great degree turn you off to the Church as a whole. She is a hospital for sinners.
God be with you.
