I'd say it's more 'occasional barbs' than 'constant bitching', and I'd say that given some of the skullduggery that has gone on over the past 12 months, it's within the bounds of being reasonable.
Without speaking for every Saints fan, which we know would be impossible anyway, I dare say that the vast majority hold nothing but admiration for much the work Gilmour did for our club. But there are nuances, and things change.
My honest position as of today is that, for better or worse, he's on the SMISA board now and I hope his experience is proving to be of benefit to St Mirren. By the same token, will I turn down the opportunity to make a quick jab on social/a forum? No, because that's my personality and nobody has the time to caveat everything they write with 'we know he saved the club twice etc etc..'
Edit: didn't see your post.
Precisely. I think there's room within the middle ground to take the piss a bit.
