Depends on what ideological stance is. I knew people whose ideological stance was that Jews rule the world and are dangerous. Including all the consequences including mild "holocaust was basically necessary". Perfectly charming people, super easy to get along with. Of course, unless you insist on claiming that Jews were treated badly and unfairly. When you oppose them about that specific point, they get quite aggressive.

It is easy to get along with people of various ideological positions, as long as you are willing to nod along, regardless of real world consequences of their ideological stances. As long as their opinion is the one ever said out loud.
