Because nothing says "serious political movement" like calling a prominent politician (in this case the retiring Barney Frank) a perverted sodomite piece of shit. I looked at the Tennessee Tea Party's website to see how homophobic cussing aligns with their stated goals, but I just can't tell.
A return to Constitutional values and a reaffirmation of state sovereignty
A call for fiscal conservatism and a low tax burden
Individual liberty and personal responsibility
To encourage and assist those who hold these values to seek elected office at all levels of government.
Is deriding someone for being a perverted piece of shit an example of individual liberty and personal responsibility? Maybe it's an example of Constitutional values? I wonder other things, too, like what a non-perverted sodomite piece of shit would look like. Would it be unfair to ask all politicians who work with the Tennessee Tea Party after this if they also believe gay people are perverted sodomite pieces of shit?
You'll be unsurprised to learn that the Tennessee Tea Party encouraged followers on Facebook to thank their representatives and senators for passing HB 600/SB 632, you know the bill that keeps Nashville from protecting the perverted sodomite pieces of shit employed by city contractors.
The fact that a major political player in the state feels free to dehumanize a whole group of people and call them perverts and sodomites and pieces of shit in public without giving it a second though exactly illustrates why gay people need legal protections from discrimination. Some people in this state have trouble even viewing them as human.
