Eating Tomatoes is STS

[Minyatur]

Why do people react so much at your signature? It is because it reflects an inner conflict that is in them, else it would get no attention. 

Maybe it could reveal inner conflicts in some people, speaking of tomatoes would be rare, but I've read an article of a man who didn't eat or drink for 70 years, I guess this type of entity would feel bad about eating vegetables too, and does not wish to sustain his existence by taking from the Earth.

Let's take it a step further. Why do you suppose they have an inner conflict about eating meat, but not about eating tomatoes?

Because they call it silly, but as you stated it can be possible.
