Every endeavor has them: people who selfishly claim their “rights” to this or that even though its harmful to others trying to do the same thing. A good example is flying from a sensitive site and tearing it up–making lots of noise and inflicting on one group of people. They will complain, the site owner will be pressured to say “no” to paramotoring, and everybody loses.
In our sport there are two primary contenders. One bills himself as “instructor” but is horrible for most of the unsuspecting people who think “that free training” is remotely a thing. The other is (or was) horribly disrespectful of sites but may have come down from that (as of 2019). Both make many completely false claims that are easily falsifiable.
