Political views have never been much of a problem for me. I’m strongly opinionated, but I also work in the public sector, which means I leave my personal political views completely out of my professional life. That is certainly a form of self-censorship, but even though it it’s forced upon public servants, I can’t think of a single time I regret keeping my political opinions to myself. There are certainly political movements I wouldn’t work for, but over all it rarely seem like a good idea to get into politics unless you actually want to make a career out of it.
Just write about your favorite hobby. When I started my personal blog a decade ago (yikes...), I chose a topic and made a rule that I would stick to it. No politics, no tech, no personal drama. I still enjoy writing about it, and have almost always stuck to the rule, so I don't think an employer could take offense at any of the several hundred thousand words I wrote.
You want to maintain a certain image for employers and that restricts your freedom to rant.
I don't point potential employers to my personal website (which I also don't associate with my real name). It's just none of their business. When I want to share work that I've done, I put it into a standalone presentation that I provide on a memory stick.
Or worse, you expressed an off-hand opinion about some social issue back in 2006 in an otherwise technical blog post that the wrong person stumbled upon and now the world is going to cave in on you.
I would love to write more, but censoring myself for the sake of future employers, psychos, etc. tends to make anything I do produce come off as bland and uninteresting.
