"Having a political view" contra SSM might not only take the form of "non-heterosexual marriages are icky." Engaging in caricature doesn't help advance the discussion of PC in the workplace. People might believe that homosexual marriage isn't morally or ethically legit. That a company or large numbers of people disagree doesn't mean the people that have these views should be punished for thoughtcrime or for expressing their opinions, or donating to a non-PC cause.
