> would you act differently if this person were not a co-founder?

I have several colleagues who I'm fairly certain are anarcho-syndicalists, meaning they want to abolish the state and capitalism. I don't know about my colleagues, but in general anarcho-syndicalists seek to bring about their vision through organising trade unions, and use that to seize control of the means of production and distribution. I on the other hand am clearly a capitalist pig seeking to oppress my workforce. Why else would I invite them to join me on the barricades against mass surveillance and censorship? Shared values around privacy? :P

I have no business questioning which demonstrations my colleagues participate in, or what they write on their blog. As long as they are not actively malicious against me, our workplace, or their fellow coworkers.

It's getting late, maybe I'm missing something in my description. I guess that's a rough approximation of how I feel about tolerating differences of opinion.
