"you guys never use the term 'far left wing' "

... and you guys never use the term "far right".   Listen to Rush, Ann & the rest of the clan and you will hear them often refer to the "far left".

Grow up!   It is just a joke. Extremists on both sides seem to be loyal to their "cause" and start taking offense when someone pokes fun at them.

Frankly, all politicians are open to satire.
