How is it a reality that you HAVE to make peace with? I've been interviewing a lot lately, and the vast, vast majority of workplaces have no problem with me running Linux as my daily driver. Most even offer Macs.
I can relate to your pain. At a previous position we had special windows workstations to deal with all of windows-specific software, and all of our personal workstations were using linux.
Now that I manage teams, I don't care about what OS people use. The more productive they are the better. The only dev (over 15 people) that used windows told me after a few months he regretted keeping windows on his machine !
