Ridiculous Threats

Is it just me, or do you find it ridiculously funny (because it doesn't make much sense) when certain girls are trying to "protect" their friends. Example:

GIRL: "You better be careful when you're dating her (referring to her friend). If you hurt her in any way, I will go over there and hurt you myself. You have my word."

COMMENTS:
#1) umm, unless you are Ms. Butch, world class American gladiator, I don't think a girl is physically stronger than a guy. even if the guy is a stick, very unlikely to overpower him.

#2) What if it's the girl that hurts the guy? Does this friend still go after him?

#3) What's with the threat?! Doing that will probably lessen the chances of the guy opening up to this potential girl's "friend".

GIRL: "I don't want her to cry to me again when she gets hurt. If you hurt her, I will chase after you and get you back for it."

COMMENTS:
#1) Again, on average, girls are not faster than guys - physical limits. (Just like how humans can not outrun jaguars.)

#2) Are you just a fair-weather friend? When your friend's going through a hard time, are you not going to be there for her?

#3) Are you implying that all guys are jerks and they are the ones that are to be blamed for anything that goes wrong?

I have observed that girls who have this protection barrier around their friends are typically the ones who got burnt before by some guy(s) in the past. And because of that, have a skewed mentality that all guys are like this. But I actually have proof that not all guys are jerks (just pervs, haha). Meet DS, my perfect guy...
