They're arguing the wrong point. Instead of pointing out racism, you should be asking how Trump would be treated if he said something like that. It would dominate the news cycle and people would be demanding he step down over it. The point is not that she's racist, is that the double standard is so obvious even ray charles can see it
Good, that's exactly what the second amendment is for. Most synagogues have armed guards anyway. Churches should have them too. Im sure there are plenty of good christian 2A guys willing to be armed ushers
