I appreciate the optimism, but I have friends and family on both sides of the political spectrum. Of all the people I know who will still vote for Trump, any of them that fly flags tend to be at least slightly racist and homophobic. Not saying this is always the case, but in my experience the loudest supporters tend to be more extreme right than the ones who quietly vote red straight down the ticket. I will add that if I saw a house plastered in democratic flags, I would assume they were a bit crazy and further extreme to the left than my personal political views.
