People Who Think Opinions Can Be Wrong have realized that opinions, despite popular belief, can indeed be wrong.
If you have an opinion that is based on your skewed and/or otherwise warped personal experiences instead of one based on well thought out research, your opinion is invalid.
Keep in mind, however, that "opinion" is different from "taste."
Example A:
"I think that Britney Spears is a more influential musician than Mozart or Bach."
This is a wrong opinion, it is neither backed up by research or facts. Anything coming out of this persons mouth you should take with a grain of salt.
Example B:
"I like vanilla ice cream more than chocolate ice cream."
This is an example of "taste" and it, unlike an opinion, can't be wrong.
