And my final reply was follwing:

If you are so passionate advocate of nudists then you can tell me those "conclusive" evidences in their support which I have not been told so far.

There is one way to know what early humans actually did. It is to see today's or about a century back's aboriginals. What they did? Did they or do they not use at least some form of dressing? You can see ancient tribes of Australia, Africa and Latin America for PROOF. All of them live in warm environment but still use some or the other form of dressing. If they get inadequate dressing then they do paint their bodies so as to reduce the impact of nudity in them...!

And I don't follow Whatever I am told!

And ... Shame is not any repressive feeling. To be "shameless" is NOT to be "confident". To be "shameless" means to be SHAMELESS...! Honestly however, shameless doesn't mean to be like animals as animals are not so advanced to have such advanced feeling like shame. To be shameless is a form of evil however. Because shameless people intentionally try to copy what inferior animals do!
