While there was a "reductio ad absurdam" in there, it appears that term was used in error. From the rest of the post, the complaint appears to have been about an alleged "straw man argument".
I have no comment on the issue, I just wanted to point out a terminology confusion.
You are both right. My use of the term was in error. I meant to say it was reduced to absurdity while being presented as an inevitable logical conclusion, which is a straw man argument.
Without the straw man, reductio ad absurdum alone is just a tool, not a fallacy, as you say.
