What are you, furfag incarnate?
I know what the thyroid is. :|
You could push someone, maybe punch or kick someone, but... jamming your finger into their thyroid? What?
Eh, it just takes less energy. If someone comes towards you with a hug, just put your finger in front of their neck. If they're smart, they will back off. If not, they will face the wrath of my finger in their thyroid. You could compare it to someone running into another's fist.
It is more of a "back off" method. If you want to go bending people's legs behind their back, in their mouth, and through the rear, go ahead, that's your choice.
OK I'll give a serious answer on this one.
For me, showing empathy is a rather difficult thing to do. Apparently, Autistic people, such as myself have a hard time expressing it (although this may not count for all Autistics) coupled with nine years of family violence, a family that empathizes having a thick skin is good, a rough school and social life, it's not hard for me and others I know to understand why it's hard to express it.
The only time I can really express it - is between people I love the most like my immediate family (brother/sisters).
So yeah, I'm a little broken in that sense, but far from incapable of expressing it.
