It is adding incendiary meaning. You are assuming the intent of someone else not wanting politics in the workplace. You assume it means that they are content with the status quo and would like to maintain that.

The reality is that many people keep politics out of the workplace because they dislike the amount that bringing politics to the workplace can affect the cohesion of their team/department.

You're creating a strawman argument.

You clearly value the change that can be brought by bringing politics into the workplace. That's totally cool, your value system is different than that of some other people. All they're asking is that you take their viewpoint without assigning your assumed reasons to it.
