Zero ... they wouldn't be here would they ...
Ask yourself how many forum users have also been helped or had their issues solved by GARY "I don't sugar coat anything, but I don't hold a grudge and I'm direct because I'm honest and I'm not here to fluff you"
Everyone here is entitled to their opinions and entitled to express their opinions. Yes, sometimes lines are crossed. People can report a post and a moderator will look into it.
"No Sugar" hasn't said anything which is actually offensive. He's only been direct. Sometimes people don't like that, but it's a forum , you shouldn't take it personally - you can't read many of the emotions which are there when it's written. You can ask questions and find out more. Personally, I find if I read his posts in a Scottish accent they sound soothing rather than aggressive .. (but not .. really really soothing ....

)
Or you can just click ignore and they will cease to exist in your own little private forum world - though you'd also miss out on any useful information that person gives out. This is what I don't understand - people complain they don't like what someone writes - they have the option to not see it - IT'S THAT SIMPLE !
If you were to take a moment and think about what's actually offensive or not, you certainly wouldn't be labelling another forum user as being the leader of the Nazi party.
