5chw4rtz has the best response to COAST comparing 9/11 terrorism to the Streetcar in a Twitter post. Here is a pictorial version of the tweet:
Yes, the anti-city group went there and did it on the tenth anniversary of 9/11, and they tweeted more about terrorism and the streetcar beyond this single tweet. They lied and are totally full of shit, but they went there. That says miles about their lack of character and willingness to lie and slander others. Sure, they'll call it a joke and maybe they'll take the offending Tweet down. They will not admit they were wrong. They really need some counseling. Beyond a public apology from the group's leaders, the person or persons running the twitter feed should be replaced, if any attempt to show dignity exists within that group.
If there are elected officials who support COAST, even in the slightest, and they don't PUBLICLY condemn this and the other similar tweets from COAST, then they are going to be called out as tacidly supporting it. As the maxim goes "Qui tacet consentire videtur" (he who is silent is understood to consent), which holds true doubly here for the political climate of the times.
