Anger at Trump rally (Twitter)

Videos taken of Donald Trump supporters outside a rally in St. Louis, Missouri, show demonstrations of extreme anger, provocation and aggression as the GOP front runner tries to defend himself against criticism that his rallies are becoming dangerous.

According to the St. Louis Post-Dispatch, a massive crowd of thousands waited in line to hear the former reality television star and real estate mogul speak downtown at the Peabody Opera House. But protesters were also in attendance, as become commonplace at Trump rallies.

"We're just trying to join with the Muslim community saying hate speech has no place here," Jay Kanzler, an Episcopal priest and attorney who was among the protesters, told the Post-Dispatch. "We stand with our Muslim American bothers and sisters, our Jewish brothers and sisters, our Christian brothers and sisters for this community. We're not going to let Donald Trump's hate speech divide us."

Trump supporters hurled foul language and hateful words at them. Watch video of high tensions, as posted to Twitter by witnesses.
