How would MAGA world react if a Muslim killed 10 white people and had issued a manifesto full of hate about whites?

Ha ha ha!! I'm SURE that's happened a few dozen times already. MAGA country already has responded to that I am sure (due to a past incident or two)? There tends to be sorrow for a lack of life no matter if it's black, white or some other mix of minorities and white. Just like you'd see from ANY other group. I could point to more than a few notable MAGA members who are known in the community who aren't white and/or not just "not white" but Muslim, Jewish, Sikh, etc. MAGA is a much more diversified tribe than the left sees us or paints us as. That sort of bias is REALLY going to bite (in the ass) the Democrats in the USA and the Liberals and Socialists in the NDP here in Canada. The blanket misunderstanding and extreme bias is a huge weakness in my opinion.
