Well I didn't get that from, "I'm sorry". Be more specific. Don't mean to be rude, but it's annoying and I perceive it as condescending when people say "I'm sorry" after making their point in a disagreement.
I don't care if the cops disagree with me. I care if they use violence against me for disagreeing with me, when I am doing nothing violent or threatening towards others.
Should I be arrested for disagreeing?
That's exactly what this situation is.
Civil rights protesters were hosed down, dogs were sicked on them, etc. I am sure a lot of other people said they were retarded for bothering to protest against something so stupid, banal and trivial, also. The fact that you think that segregation is so obviously wrong is revolutionary compared to what the majority of people thought 100, 60 years ago.
