Cutting people out of the fight before they can try in this manner is discriminating. Fact of the matter is, some players need to be carried by others to clear certain content.
People are not entitled to be carried, though.

What's wring with using it to discriminate? Would you invite a 4.5k HP tank to Turn 5? So why is it okay to invite a 150 DPS player?

Discrimination in a PF group is fine. You play with who you want to play with. I'm not sure why people get up in arms about that fact, and why "anti-elitists" feel the need to force themselves into groups that they are not a good fit for.
