Another reason why people's donations should be anonymous

From the Weekly Standard:

Businessman Frank Vandersloot, the CEO of Melaleuca, has been targeted by the Obama campaign after donating money to Mitt Romney's presidential campaign. . . . Mr. VanderSloot was one of the eight, smeared particularly as being 'litigious, combative and a bitter foe of the gay rights movement.'"
The attacks are working. Vandersloot revealed in an interview on Fox News that his business practice is being hurt by the attacks from the Obama team.
"Those people that I know well weren't affected by this [attack]," said Vandersloot. "But for people who didn't know me, who are members of our business or customers, and they were reading this, then we got a barrage of phone calls of people cancelling their customer memberships with us."
"Really?," the Fox News host asked. "How many did that?"
"A couple hundred that we can track," Vandersloot replied.
Again, the host asked, "Really? Do you have any grounds to sue?"
"I suppose we do," Vandersloot said. The businessman says he's been accused of being anti-gay, an accusation he says that couldn't be further from the truth. . . .

Is it serious that people who oppose Obama must be doing this because they are anti-gay?
