I think the downvotes is for essentially doing what you are criticizing when you point out a certain thing someone said that hurt you.
They were making an effort to stay on topic (reliability issues with Tesla's cars). You're making it about divisiveness.
The ethical considerations around Tesla are pretty bizarre. It gets political, since the owner of the company is so deeply associated with both the cars and politics.
I don't think your comment comes from a bad place, I understand the fatigue and the desparation. However, when someone in power does something "divisive" (quotes, because its the understatement of the decade - you can probably come up with examples) and people who mention it, even by not mentioning it, are told to be quiet because they are being divisive - it can come off as trying to silence people and ensure no criticizism can be raised.
Again, I don't think that was your intention but it has that effect either way.
