Mactach...
Obviously doesn't possess a terribly extensive vocabulary or, knowledge of the English Language.
If you notice, most of their "comebacks" to anyone making valid points on this, or certain other boards I've seen, seem to be a maximum of 4 words, example "What's it to you?" or "Why does it matter?" VERY basic...
If Mactach is having a particularly trying day and doesn't feel like talking, you'll still get a "shut up" out of them...
My vocabulary too, is fairly limited to a maximum 4 words, as shown below.
