I agree that there are reasonable points, that was the purpose of my comment, I thought the poster had something to offer, but am of the opinion that people won't take them seriously because of their approach.

Emotion is even a valid addition to the conversation if they thought it added to their point. What is unproductive is expressing that emotion by calling a car brand "absolute cancer".

I think it's valid to be upset about Tesla as a brand. I think it's valid to call out repairability issues. Coming across as hysterical means that people won't take you seriously despite that.
