People thinking Stallman is a jerk doesn't excuse you. You are responsible for your actions, as Stallman is for his. The reason you seem disrespectful is because you expressed several assumption that all people here are ignorant. You did it even in your first post, before actually hearing anyone's opinion on the issue. This isn't constructive in way, so it only servers to insult people.
I agree with you that the predominant hardware companies are unethical and should not be supported. I agree with you on all the issues you listed that result from the unethical behavior of those companies: Patents, planned obsolescence, non-compatible batteries, anti-features, secrecy on how hardware works, etc. These are typical harmful ploys used by such companies against us for their gain, and are obvious reasons why we should fight back. I DO agree that it matters what CPU we use. I just don't agree that my AMD CPU is significantly slower with free software, or that this is the most important issue here. Wherever is faster or slower, when I buy a new computer I'll still want to buy from someone who doesn't strive to screw us, like Intel and AMD do. I was thinking of buying a Lemote Yeeloong, which uses a MIPS CPU. When the time comes, I'll also consider other computers, such as the those listed on http://www.qi-hardware.com/.
