Consider the possibility that people can like Macs for reasons entirely unrelated to Apple's marketing tactics. Reasons can include things most people would agree are legitimate qualities to look for in computers, like build quality, display quality, keyboard quality, performance, battery life, etc. Those seem to me as more legitimate and less "fanatical" reasons to prefer computers from a particular manufacturer than the reason you provided, which is that you dislike some (certainly not all, and likely a vanishingly small portion) people who also buy computers from that same manufacturer.
