A debate started when one of my competitors started to talk about getting his business involved in some recent political debate in a non political form. I disagreed with them on business getting involved.
Here is a report here on just how disastrous it can be.
According to the report somewhere between 25% to 41% of the population will stop doing business with you, if they do not like your politics or business practices and 59% of those that leave will never come back.
Do not do it, it is dumb.
