Not at all, even I use Linux on occassion. But there are a lot of leftist whackos deeply involved with Linux, starting with "the father of free software" and green party advocate Richard Stallman. The DNC runs on Linux, every communist government on earth is standardizing on it, but most of the linux pushers will do everything they can possibly think of before ever admitting any possible connection. Just be truthful, don't run around creating 20 threads a week full of bull then try to deny the obvious.
There are a lot of leftist whackos deeply involved in Windows (Gates, Ballmer) and Apple (Jobs) as well, and I wouldn't be surprised to see that Sun has a few on their staff as well.

So does Free Republic.
