No - I agree - sorry if I didn't answer you before. There's a place for legitimate use of semi-automatic rifles for hunting etc, though personally I always used bolt action high power rifles, for a few reasons.
I'm very uncomfortable with the concept that *for pleasure* people would use an AR15 etc to hone their skills in getting as many shots on a target in as short a time as possible.
I am not entirely sure that it is such a morally significant distinction that semi-automatic rifles aren't necessarily designed solely to kill people (as opposed to fully automatic/auto capable ARs), as your interlocutors (I am using that term loosely) seem to think. If there are adequate/sufficient replacements for hunting purposes, as the independent Thorp review found in 1997(?), then I would argue that the trade-off is worth it. At the end of the day, in a first world country with high average income by world standards, most people only hunt for predominantly entertainment purposes.
