Most people's views on this just come down to political ideology. I think everyone should be embarrassed.
- I can't believe the gov's office actually pays somebody to monitor social media,
- I can't believe that idiot brought this idiotic tweet to the attention of the school (even if they were the host that invited him to speak),
- I can believe an 18yo girl entering college could tweet something so sophomoric (is that the word you're looking for?), but
- I can't believe that girl's parents would be so stupid as to take this to media, plastering her stupidity all over the country.
But I'll admit it, I kinda hope the University of Arkansas admissions committee hears about this and declines her admission on grounds of sheer stupidity. She comes across as a complete moron both in her tweet and her interviews.
