What would Jesus do??? Good question, that I as a sinner am not qualified to answer but my thoughts are these........
Ultimately the 'actions or activities' that go against God's Word are sins and we are to hate those sins and abstain from them........while at the same time we are called to have compassion on the sinner. Whatever the sin, whether a thief, prostitute, tax collector, murderer or those identifying as something other than what they were born as.
Christ called us all WHILE we were still in our sin to come to Him and His Grace and we as Christians are called to do the same. Hate the sin but love the sinner. It is not our place to judge others, that is God's job to pass judgement and if we do judge others, then we risk being judged ourselves
Admittedly it is a difficult thing to come to terms with in such a crazy world we live in that goes against everything we've ever known or been taught. I guess it gives something of an understanding to the world when compared to when Jesus came the first time..
