This thread is about his actions.
Not quite, this thread is about your eraction to his actions. You might not like that, but he didn't post here and he is not making this an issue in this community.
I don't mean to be condescending so this is just a comparison, but if my daughter came to me and said that a neighborhood kid had called her a bad name, I would be more concerned abot her emotional state because she is part of my family and I can do something to address her emotional state, but I can't do much about the kid and what he said.
You post a message about your offense about what you see as an insult from someone else. Well, he's not a part of this comunity and I can't do much abot what he said, so the only part of that dynamic I can address is your reaction to it. And frankly I find your reaction to the situation confusing at best and, wekk to be blunt, immature. If being called a "democrat" were to be considered an insult, then you might have a point, but it's not. So for someone to say "democrat" instead of "democratic" and to take it as an offense, whether intended or otherwise is... not rational. (I use lower case intentionally since in the context of the original quote, since it is spoken, there is no capitalization) More to the point, even if it were *intended* as an insult, to take offense at it is *your* decision to make.
How do you explain his actions?
I don't. In this context I don't care about his actions so I don't bother to attempt an explanation. You have four possible interpretations. *shrug* Ok, maybe it's one of them or maybe it's all four or some combination. If you want to find something stupid in his words and actions, there are may more flagrant examples he has to offer.
However, back to using lower case (since it was a spoken speech), if you read his words in the quote you have two phrases "democrat approach" and "democrat goals". Now, to indicate that he is talking about a particular party and rephrase it as "democratic approach", etc...just adds to the confusion because then
'democratic' sounds like an adjective describing the approach, the goals, etc... where he is attempting to use the word to mean the political party, or members of it. "democrat goal" in this case more clearly conveys "goal of the democrats" then "democratic goals" would have.
Or he's a complete idiot. *shrug* In this context I don't care.
But if you already dislike someone and go looking to find insult in what they say, you can find it. However, that's an awfully self-defeating way to live.
