Well sure, my personal opinion is that FDR was the best American president. Not perfect, but who is?Jay and Stephen- I hope we all can agree that there is a significant difference between the removal of confederate (traitors) statues and those of FDR and Lincoln.
However, the whole point of the democracy is for the people to make collective decisions. The question of "where do we stop?" is answered by the people. Earlier you (Peter) were defending the actions of the hippies, which some might say was a social "overreaction" in their critique of that era's status quo. I'd say advancements were made from their cause, and their excesses then became the critique of the next generation.
For a music analogy, the excessiveness of Stadium Rock'n'Roll and Disco was discarded for Punk Rock and New Wave... Those were then subsequently discarded by the next generation of music artists, etc.
So I'd suggest when it "goes too far" is when a movement exhausts itself, naturally.
The fact that Peter and SDR are saying 'this is going too far' makes me think that we're seeing that exhaustion taking place... Regardless, I still don't think it's a big deal for schools in SF to change their names if they'd like.
