Here's another analogy for y'all.
You remind me of white folks who, when some racist piece of shit does something racist, instead of castigating the racist with the understanding that the group of white folks that that racist sack of shit is being associated doesn't include them if they aren't also racist sacks of shit, instead fight against the notion that there is a larger problem that should be addressed because they feel that what they have in common with the racist sack of shit means they are also being talked about.
Which just makes them look like they are since their entire focus is on defending the group instead of commiserating with the victims.
You don't have to associate yourself with these assholes just because you like Sanders. But pretending these assholes don't exist and trying to fend off castigations of these asshiles has the effect of making you look like you're one of them.
So maybe try and not do that, yeah?
