Given DU-folks' assumptions about Rs and conservatives, it's obvious why they assume the perps are Trump supporters. OTOH, false-flag faux hate-crimes have been quite frequent of late.
Conservatives generally wouldn't believe in vandalizing chapels. Many are at least somewhat devout Christians who have respect for sacred grounds.
Also, if it were apparently anti- Semitic, why would it have been sprayed on the chapel rather than on a nearby synagogue or something?
Most definitely false- flag, to portray conservatives as monsters.
