Better than you have tried methinks.
"When people post here calling them corporate sell-outs, or DINOs, or traitors to the liberal ideals, I think we as a community should come together and point out that person is wrong, and if they persist we can politely so them the door."
The Blue Dogs are fucking DINO's!!!! What part of that don't you understand?? By the way, I copied the following from your profile - it's your quote -
"Speak truth, even if it doesn’t support your point of view, at least you can hold your head up high and look others in the eyes." Try implementing it!
