The person you responded to literally said "ignore all those things without it mattering", citing how it does, in fact, matter to some people.

If OP wants to unplug, fine, but as the saying goes, this isn't an airport - you don't need to announce your departure, or in this case, filtering of such posts.

By making this post, OP has upped the ante, in a potentially insensitive manner, whereupon their privileged status (presumably white and if not well-off then at least not very poor - or possibly not even living in the USA:-P) was brought up as being relevant. At least people are explaining, rather than merely downvoting.
