"I couldn't believe BART would allow something like this. Why are they doing this?''
Yeah, why can't we live in a world where only leftists are allowed to express themselves and anyone with a dissenting viewpoint is sent to a re-education camp?

Uh, maybe because the right to free speech actually is in the Constitution? Why should anyone respect fake constitutional rights if these people refuse to respect real ones?
