While I am claiming that A: "I personally do not like / object to X based on subconscious etc. reasons" leads to B: "X should be illegal" all too often, I am not claiming that B: "X should be illegal" necessarily implies A:"(...) because of subsconscious etc. motivations".

Does that explanation help?

Do you also think that liberals oppose guns, GMOs, and fission power plants out of a desire to protect their personal identities? Or do they actually have some reasons to be concerned?

In part, yes. Nothing better for building group identity than a common enemy to rally against. There are legitimate actual reasons, but looking at protestors chaining themselves to train tracks to stop trains with fissile material, I'd doubt they are driven mostly by rational reasoning.

Personally I disagree with the people who are afraid of self-driving cars.

So do I. I'd be happy to be an early adopter.

I didn't aim to set up an absolute dichotomy, I'll reread my previous comments for clarity. It was merely a reason among many (two of which I expounded upon).
