You are right about how change comes about. It is just that there is a time and place for it. I said that the role of the ideologue is to introduce new ideas to society, not to harp on them constantly when and where they want without restriction.
A line is crossed when they come into the workplace and make wrongthink a fireable offense. The proper place for these things to be worked out is, for the most part, in the media and on discussion boards like these. Or in private conversations like the bar. The key to understanding this is in the word "workplace": it isn't the "socialjusticeplace" or the "inclusionplace".
Conservatives have their place too. The role of progressives is to introduce new ideas. The role of conservatives is to present the argument about why these new ideas might not work. "Change" is not an automatic good. For example, all of us will undergo the change from "alive" to "dead". Personally, if it were within my power, I'd prefer not to undergo that particular change.
If I could wave a magic wand and create a space for conservative and liberal ideologues to beat each other senseless, and leave the rest of us out of it until the winner is decided, I would certainly do so.
