I was at least willing to consider your perspective if you’re talking about state sponsored memorials that may no longer pass the PC sniff test. Germany isn’t the US, so really bad example. Also, public street names vs a private citizen choosing to fly a confederate flag, third reich flag or some other offensive symbol is wayyyyy too broad a net to be casting. We all have the right to be as offensive and un-PC as we want as long as we’re not using public funds, lands, etc to do it.
So, if you want to make your point effectively try to acknowledge those rather important discriminators else you just become one of the snowflake crowd unwilling to accept the possibility that being offended and moving on with life is just part of living in a free society.
