That looks like a calculated non-apology. An actual apology probably doesn’t exist. He said “I’m sorry if anyone was offended”. He placed the blame on the reaction that others had to his abhorrent statements, not on his actions themselves. He didn’t seem to care that he was in the wrong, only that the reaction from the people was politically inconvenient for him.
I’m a former middle school principal and I hate and avoided the word “Bully” and “Bullying”. It is one of those words that is insanely overused and thrown around. In most cases, kids engage in relational aggression and then one kid takes it too far (intentionally or not) or can “dish it out” but can’t take it. There are some cases where kids will single out the “weird kid” but that is far more rare than relational aggression and much easier to identify and punish. The parents of the those aggressors usually are mortified by their own kid’s behavior unless that kid is being raised by sociopaths.
