This is partially true but irrelevant. People don't join a club so they can experience body language. I assume they go so they can form a community and interact with people who share the same interest.

If visual contact was essential for forming significant relationships then the blind would be unable to make friends.

I think they do actually. Otherwise, why would people go through the trouble of meeting physically when they could do it on the Internet? It's not like people who meet in real life don't know about the Internet (I'm thinking of tech conferences, HN meetups, etc.) The physical experience is simply better.

How do blind people get impressions of what we see with our eyes? They use touch, as well as the other senses.

What can be learned by a blind person touching an avatar on a computer screen?

People eat orange because they are hungary and orange taste sweet, in the process though they get vitamin C. Is the fact that they get vitamin C diminished by the fact that they only ate it because it tasted good?

Would orange flavored candy be a sufficient substitute here? I'd say no.

"If visual contact was essential for forming significant relationships then the blind would be unable to make friends."

Maybe the blind are much less successful at making friends. What is your evidence to the contrary?
