I never claimed you did say that. But you introduced the notion as something "one could argue", and the only thing I'm attacking is that notion, not you personally. That's more than you can say for yourself, incidentally.
That you took it personally says far more about you than it does me. When one puts forward a notion on the basis of "one could argue", sometimes it means it's a notion they're not especially attached to but they think is worthy of consideration. Other times, it means they're evading personal criticism for believing in that notion. In the first case, one would not feel so worked up and personally attacked by having the notion criticized; in the second case, they would. Your reaction, I'm afraid, has given you away.
