“We want as many people as possible participating if they share our principles and values.”

Principles = Say and do anything to win.
Values = Winning isn’t just the best thing, it’s the only thing.

Subtext: White-collar criminals, organized crime associates and Joe Isuzu types will especially feel at home with us.

HTH.

They’ll welcome you into the party if you share their principles and values

Well, duh.
