Did you though? What was your method? Making observations? Did you make measurements? Did you make an effort to find your blind spots and search those as well?

You can say that you believe the anecdotal evidence you've observed is sufficient to come to a conclusion. But please, do not claim that you've designed an experiment. You (probably) haven't.

For what it's worth, I think you'd probably find that conservatives have more irrational protest behaviors than liberals, but then again, the trick is quantifying and measuring it.
