Another example for why campaign donations should be anonymous

With the flood of unidentified donations to the Obama campaign, it seems that a huge number of donations are de facto anonymous.  Indeed, anyone who followed the attacks on donors after California's Proposition 8 knows the problems they faced.  While this isn't strictly campaign related, this example shows the attacks people face when they reveal their personal opinions.

A family-owned Christian bakery, under investigation for refusing to bake a wedding cake for a lesbian couple, has been forced to close its doors after a vicious boycott by militant homosexual activists.   

Sweet Cakes By Melissa posted a message on its Facebook page alerting customers that their Gresham, Ore. retail store would be shut down after months of harassment from pro-gay marriage forces.   

“Better is a poor man who walks in integrity than a rich man who is crooked in his ways,” read a posting from Proverbs on the bakery’s Facebook page.  

“It’s a sad day for Christian business owners and it’s a sad day for the First Amendment,” owner Aaron Klein told me. “The LGBT attacks are the reason we are shutting down the shop. They have killed our business through mob tactics.” . . .

No one minds people not shopping at a particular shop, but the attacks here have gone well beyond that and have been malicious.

Within days, militant homosexuals groups launched protests . . . . Klein told me he received messages threatening to kill his family. They hoped his children would die.   

The LGBT protestors then turned on other wedding vendors around the community. They threatened to boycott any florists, wedding planners or other vendors that did business with Sweet Cakes By Melissa. . . .

My question is whatever one's views on whether marriage should be between a man and a woman or between any set of consenting adults, why isn't this type of threats of violence and other actions condemned?
