If the worker has swastikas on his FB page fire him immediately and inform the FBI.

I think what we are discussing here is more nuanced in nature. As in someone has an opinion on issue of the day and someone else feels that political issue defines them. It could be homelessness, taxes, or something else.

If someone interrogates me about a political topic I might tell them my opinion or I might tell them I haven't thought about it. Of course someone may get very very angry about the latter.
