Consider the situation where I am billed by the Boy Messiah to pay for someone's abortion, drug rehabilitation or Birth Control. If I can opt-out, your ilk would whine that it's unfair because now your part of the fees will be higher. Tough sh*t, sherlock.Consider the situation where the legal fee to create a contract in a company of five employees is $1,000 and one of those employees chooses not to pay his share. Then instead of five workers paying $200 each, four must pay $250. That freeloading right-wing bloodsucker has effectively stolen $50 from the other four. I'd suggest that union members take whatever action necessary to protect their property from these thieves.
If you wish to support a Socialist Party masquerading as an "agent" representing workers rights, that's fine. Go for it. But don't force me to pay for your political fantasies.
If that Socialist Party masquerading as an "agent" representing workers rights wants to convince me that it's in my best interest to join them then let them make their case without using baseball bats but civil discourse. If I like them, I'll join. If not...Hasta la vista.
