I never said or implied that all users of semi-autos were slobs. Why would I do that? That would include me!The claim that all users of semi-auto rifles and pistols are "slobs that tear up ranges and woods with rapid-fire, and leave trash behind", casts aspersions on an entire class of people: all users of semi-auto firearms. It is a classic ad hominem attack.
Ad Hominem Attack:
A rhetorical strategy where the writer attacks the character, motive, or some other attribute of the person or an entire class of people to denigrate them.
