1 - You are absolutely right in that you are warranted to have an opinion.
2 - You are absolutely right in that you are warranted to act according the opinion you have.
But... that's where it stops.
3 - All of us here have the exact same rights, and, the majority of us disagree with your opinion. To the point that we feel like exercising our right to call it spurious or factually wrong.
4 - Even if we'd agree with you, we don't, while you are warranted to defend your opinion, you don't have the right to ad hominen attacks, and your use of them makes you look quite bad, reducing even more the already low value of your opinion.
tl/dr: Think whatever you want, we'll do the same, especially about you.
Peace
