AND you must report any outside income to them (so they can make sure you pay tithing on that yard sale you held) HOW IS TITHING CONSIDERED A VOLUNTARY DONATION?

By the same reasoning that a mission is volunteer service.

As well as being a church janitor, scout leader, home teacher etc

The truly amazing thing is how much time and money they swindle out of people for NOTHING in return.

Only in the very narrow sense that employment with LDS is also voluntary.

I like to link this to tithing and the temple. If the temple is the highest goal for every member, and tithing is a condition of worthiness to enter the temple, then how is tithing voluntary? In what universe is a firm expectation of member behavior voluntary?

"Isn't it ironic that we are not supposed to sell our tokens for money when we had to pay ten percent of our income to get them?"

You can be compelled to join a union as a condition of employment. Same thing -- X percent of your money goes to an organization you may or may not agree with.

Tithing is voluntary because the job is one you elected to take. Institutions can and do have their own cultures that they expect you to fit into. If you go to work for PETA, they'll expect you to refrain from eating meat in the workplace, or wearing leather clothes.

At the end of the day, you take the job, you take the stupidity that goes with it. I worked for a new age-feel-goodery-chiropractic place, and put up with endless amounts of meditation meetings, political diatribes, and the like.
