They are suggesting you should "Please refrain from insults", as is clearly stated in their comment. Insult != Criticism.
Trump is more orange than just about all people.
That's a fact.
"His Orangeness" actually does the following:
Implies egregiously sized ego
Implies royalty
Associates that to the orange fact.
The connotations associated with "His" are not complementary.
Etc...
Burying a fact amidst snark, then ignoring the snark is a sleight of hand others find easy to see as well, which is how I saw your query.
Actually making facts the priority is a lot more healthy and productive, and there is a bonus!
When we do that, we can also be perfectly reasonable and also point out that any offense taken isn't on us. Sometimes facts are painful, right?
These are the things people are trying to get at so the discussion is higher value.
That's my take for what it's worth.
