Where were you 10 years ago...Hell 2 or 3 years ago? You are just noticing it now. I'm not naive, i know what is what.
I’ve noticed a shift in public acceptability and many people have too, and while it preceded trump maybe by a few years at most, he was the culmination and the catalyst for bringing it to the mainstream. The altright has been around maybe two years in its current iteration and now they feel emboldened because their guy is in the White House.
No one is saying racism didn’t exist, but there was a certain shame that these people would feel when outed for the most blatant racist actions. Now not so much.
Once again no one is saying that racism didn’t exist or that it’s even worse. But the blatant nature of some of the most non subtle forms of it such as calling someone slurs in their face, has increased. Now the more subtle stuff such as the system of white supremacy and laws that are enacted to harm black folks hasn’t changed and the clock is ticking all the same.
