I don't think accepting the fact of evolution deserves a label.
Neither do I, but when a person takes every opportunity they can find, to assert their passionate crusade to make all creationists or believers in g-d, see THE TRUTH, that goes way beyond 'accepting the fact of evolution'.
Making derogatory comments about the idiocy of people of faith, and jeering and laughing at them, goes far beyond 'accepting the fact of evolution'. It is the essence of forcing your own conclusions on others, and belittling them because they have their own thoughts and feelings that are different from yours, that defines a bully.
