When you say "what my church is allowed to teach" it touches on the #1 reason I, as a Christian, am so outspoken against him. Why does it matter what your church is allowed to preach if no non-believer is going to be willing to hear what you have to say in the future because you didnt publicly speak out against someone you rightfully describe as a "disgusting person" and someone you say you see "in no way a role model". By not speaking out you need not worry about the liberals silencing you and your church, you have already silenced yourself to those non-believers who are watching.
The article linked above says it perfectly. "Consider what an unbelieving world will say if you continue to brush off Mr. Trump’s immoral words and behavior in the cause of political expediency. If we don’t reverse course now, will anyone take anything we say about justice and righteousness with any seriousness for decades to come?"
