Six seat tables

Just reading a freeroll thread where someone was looking down on six seat tables. I am wondering will playing a six table site harm a new players game in the long run?

You need to play more loosely with five opponents that you do with nine

If you can close the deal in a sit and go, you will be fine on six seaters.

6 max = the sex imo

yes, it will teach you awful things like how to play postflop and hand-read, practically witchcraft
