Is it a coincidence?

On April 14, 2014 Laci Green tweeted:

is it a coincidence that the peace sign looks like a "V" and vagina starts with a "V"? i think not

I've seen/heard countless times, claims like "women are more cooperative than men" and "women are less violent than men" and "there would be no war if women ruled the world."

I have one thing to say in response to that:
About 5,800,000 results.

So, is it a coincidence that "violence" starts with a "V" and "vagina" starts with a "V"?

I happen to think it is, but if Laci Green thinks there's no coincidence between the first letter of "vagina" and the visual appearance of a peace sign, maybe I'm wrong and it's no coincidence those specific two words have the same first letter, either.
