There's no unbiased opinions.
In fact, to be biased is only natural.
If there's a lot of noise to show any form of displeasure, it's
always better not to feed the troll, because obviously the
perpetuator is looking for sympathy for the posts in question.
It's not about that.
Imagine if someone comes telling you that he hates A, and likes
B. One week later he tells you he likes A, and hates B.
That isn't logical at all.
