Of course not. And I think talking about strengths and weaknesses objectively is fine. CGE clearly has some weaknesses, but he is also one of the few constants in Heupel's staff. It's obvious he's trusted and viewed as capable. That's really all I need.
But yes, I do think the constant drone of Coach XYZ "sucks", "is useless", "needs to be fired", etc., is damaging. Recruits and parents read these forums during the time they are making decisions about where to go. Position coaches end up as mentors. Tearing them down serves zero benefit and absolutely has the potential to cost us recruits.
When I was young, I was as loud and opinionated as anyone on this site. Over time I've learned that I don't know as much as I thought I did and that there is value in leaving certain things unsaid. I realize that isn't in style these days, but I assure you, it works better.
