"Why is that so many Liberals claim to be so 'accepting of others' but are the first to go out of their way to go after anyone who doesn't agree with them?"
Because they are fighting a war against the Right. Meanwhile the clueless Right sits around complaining: "Did you see what they did today? Why, its just not fair!"
It's war. Engage. Stop spending any money with Leftist organizations, at least. Cancel that worthless rag called a newspaper. Start taking action. Now!
