Trumka is Damed Comunist!
In the heat of righteous passion, we all make an occasional typo. Now to your accurate point, I defy any leftist to name a single union mobster that wasn't a Communist.
The history of union thugocracy parallels that of Marxism/Leninism from the era of foreign-born Samuel Gompers of the AFL to the ILGWU's Russian-born Abraham Cahan (editor of the Socialist rag, The Forward) right up to the present with Trumka, whom you cited, and the notorious Andrew Stern of the vile, seditious SEIU outfit.
Unions are nothing more than the current incarnation of slave labor. As an ex-union member (whose proudest moment was to lead a campaign to successfully decertify the union at my workplace), I speak from experience. In Pennsylvania, a non-RIGHT TO WORK state, coerced union membership and the extorted dues paid, were tantamount to slavery. Individual liberty and freedom are always opposed by unions, and that is simply Communism.
