The whisk[e]y thing was supposed to be a glib remark- it wasn't supposed to attack anyone.
As for the muddling bit, there are a few hipster bartending trends that tend to annoy me. That's one of them. The other is the "purist" old fashioned, where the fruit is omitted and the sugar is minimized. Probably a few others as well that I'm not thinking of right now. If you pile on about how great those things are and how other options are completely wrong, there are good odds you'll get a response.
Oh, and for future reference, that's not an angry response. That's an annoyed one- the rough equivalent of

I rarely drag out the seriously angry stuff on SF. Sometimes it comes out when I'm a tad tipsy and somebody blindly posts some stupid SF trope that's simply ridiculous in the real world. I don't touch CE because the stupidity there really brings it out. That wasn't intended to be an angry post. This is supposed to be a somewhat irritated one.
