"If I didn't want a sexy sasquatch, I wouldn't have married my best friend."

I think "a few days" is the problem zone. It will be itchy and rough stubble by then (at least for me). After like a month it smooths back out. It could well be your wife telling you "this will be uncomfortable for both of us, at least wait a bit, or give me time to shave".

Smooth as silk in one direction

Severe tire damage in the other

Yeah, the third post is "Local Tumblr User Doesn't Understand Reductio ad Absurdum; More at 11."

The user isn't saying leg hair is like cancer (like fucking obviously; how disingenuous would you be to even suggest that?). They're saying the argument of "it wouldn't grow there if it wasn't supposed to" is completely stupid – that it has little discriminative power to distinguish what's good and bad if you don't already know. It isn't even nearly limited to the absurdity of that contradictory example:

"Sorry, honey, but the dick cheese wouldn't be there if it wasn't supposed to."

It's a fine-ish retort to get a seven-year-old to chill out, but it's total bullshit when you don't already know leg hair on women is fine. Pointing out that "Gravity is real because most people think it is" is a bad argument by saying "Germs didn't exist because most people thought they didn't" doesn't mean I'm trying to say believing gravity is like disbelieving germ theory; I'm pointing out the argument doesn't hold water regardless of what the fallacy (in the OP's case, a pretty clear appeal to nature) was supporting.

TL;DR: Denying the means, not the conclusion.

It's perfectly understandable if you have any nuance. "Why does it grow there [as a design aspect of your body]"

It might impact their procreation rate.

It also protects against mosquitoes

I do have MPB, but the rest of me is hairy as all hell, it also helps protect from ticks and mosquitoes sometimes....

I legit heard a news anchor say “and what it could mean for your weekend” on the TV at a bar recently, so they’re keeping it alive.

I mean not necessarily appeal to nature because the woman does not try to prove that body hair on women are inherently good. She just points out that "not supposed to be there" is as meaningless as saying "your head shouldn't be on your shoulders". The rest is personal choice (that is if you can disregard the immense societal pressure).

"Smart argument" is pointing at fallacies? What are you, 20?

Fun fact: hedgehogs aren't rodents, and are actually more closely related to tigers than to mice (by about 10 million years). Porcupines are rodents and echidnas are another thing entirely so spines developed on mammals a bunch of times.
