Why are conservatives so afraid of her?

Because they're lonely, they can't get girlfriends, they look down on women, but she's way more intelligent than anybody else they've ever encountered, and the way she smirks, she looks like that she can cut their balls off just by giggling at them. She is everything they can never be. She totally emasculates them.

Then it's more hidden desire than fear

But fear also, like I said about cutting off their balls. They find it to be very intimidating. And it's not just that she's very knowledgeable, but also that she's always looking like she's on the verge of breaking out laughing.

Last thing one of these numbnuts would want is to have a discussion with somebody looking back at them like they're going to laugh in their face. Their usual answer of "You got TDS is really not going to do much to help them in a situation like that.

She seems to have a stronger personality and this may scare them, people with stronger personality usually are cold, so it could scare people, especially people like them. The funny fact is that these fakers doesn't even know that Trump is suffering inside, they care about him for their goals. They don't know anything about Trump, still they say they support him
