You are objectively wrong. The rules explicitly state that a fence grab that has a 'substantial effect' on the fight will incur a 1-point penalty. This makes it different from other fouls, which do not specify a point penalty or DQ.
It is not the same as an illegal knee either officially nor in basic rational thought. An illegal knee harms the other fighter and may prevent them from continuing. It is embarrassing to conflate the two things.
In the history of MMA, nobody has ever been automatically DQd for a first fence grab. Ever.
So both the rulebook and precedent emphatically refute your argument.
Now, you can make intellectually dishonest arguments like another poster did on this topic, and try to claim multiple fence grabs even though it is a single incident. Or you can rely on the technicality that, yes, theoretically refs have very broad discretion. But this is meaningless in practice, where referees are expected to maintain certain basic standards of officiating.
Or you can demonstrate more self-respect than that poster did, just admit that you are mistaken about this and apologize for making the thread.
