Do you have examples? If anything there have been cases of left aligned activist employees being fired from companies like Google not too long ago. Or cases like Basecamp where they asked people to avoid politics at work or leave the company.
If that's conservative ideology, then I guess it is fair to say such ideology might not be appropriate for a workplace. In reality, he just said stupid stuff to be provocative, and tried to post-hoc justify it as vilifying conservatives instead.
