Amen, mostly for the last two paragraphs.
That being said, I think it’s important to know your beliefs and how you want them to tie into your political decisions, if at all. I personally don’t care much that the folks who attended this are driven by their convictions or passions to vote a certain way or lobby for certain laws or appointments. That’s perfectly fine and this is a democracy, it’s allowed by law.
It seems that for these folks, faith and nationalism are one and the same, or at least closely related. For me, that’s not so much the case. But, whatever the case, I do believe that political rallies shouldn’t be held in places of worship lest one forgets what your are to worship there.
