Could a factor for Donnie's behavior be related to his Grandfather's history in Germany?

[Paula Sims]

We know Donnie forgets everything except a grudge so could one of the reason's for his boorish behavior be because of what happened with his Grandfather?

Here's the link to the CNN story which Lawrence also ran one night http://www.cnn.com/2016/11/22/politics/trump-grandfather-germany-friedrich/

That and that fact that he's intimidated by women and is just plain boorish?

1. I don't think it's that complicated.

The simple answer is that he's an asshole.

2. He's a jerk..no need to look for excuses for his behaviour...

3. all of the above

He goes out of his way to belittle women so confronting a powerful, experianced woman like Merkle was very intimidating to his tiny brain.

4. He didn't even know his Grandfather...

Since his Grandpa died when his father was 13 (nearly 30 years before Trump was born)

Though, given the fact that he actually owes his riches to his GRANDMA'S hard work, and business skills, you'd think he'd realized women are worth more than beauty, and eggs.

Like others have said, he's just an asshole.
