It might help if you actually read the source you are quoting.
If you had read it, you would have noticed a rather stunning inconsistency.

Unlike some here, I do my homework. In the second paragraph Ribble says Trump behaves like a “sixth-grader.” Yet in the last paragraph you cherry-picked he states: “We actually need a grown-up, not a 3-year-old, in the White House.”

Which is it? 'Sixth grader' or '3-year-old'? You see, its inconsistencies like this that blow a hole in your arguments.

I did a little research and found this: http://www.yet-another-link-cherrypicked-and-misinterpreted-by-tb.com in the past 40 years there has not been one 6th grader that was 3 years old or younger...

As much as you progressives want it to be true, you just can't have it both ways.

Sidebar#1: I like turtles!

Sidebar#2: Interesting factoid-Ayn Rand started 6th grade at the age of 4, but they don't mention that in in the 'liberal safe-space universities'- that wouldn't fit your narrative would it?

Sidebar#3: FORMER senate majority leader Harry Reid referred to Ribble as a 'Buttmonkey-ass-hat', are you sure that you want to call Reid a liar?
