Salam alaikum.
Unfortunately we can see some of our brothers abusing scholars from innovators.
Muslims should avoid such attitude at least for two simple reasons.
1) Abusing wasn’t a manner of prophet (sallalahu alaihi wa ala alihi wa sallam) And we were obliged to take him as an example.
2) When someone abuses scholars from innovators, he can become a reason that innovators would abuse our scholars, or companions and etc.
