Good explenation. To add, this is a group of people we are talking about. Why would we allow blatent disrespect against this group of people, yet we don't allow racial slurs? "OMG BUT POLICE ARENT A RACE YOU SILLY FAG" No shit. But still a group of people. How about I say all bikers are worthless pests on the road, and I'm going to cut them off at every chance I get? Sure, there may be some decent bikers out there, that don't weave through traffic and cut me off and harass other motorists, but that doesn't matter because of a few bad ones.
What's the difference? Let's see...bikers do nothing for society, except fund our court system and bodyshops, but police do what they can to keep our cities and streets safe. Hmm....I think FTB
