'conservative' is what you'd call the opposite of 'activist'. By 'conserving' it implies sticking to the way things are being done already, or holding onto traditional values, or making changes slowly and with overall approval (rather than doing so rapidly, radically, and "in your face" if you don't like it).
What IAP is calling "conservative" is most likely "right-wing". "Right wing" is as bad as "left wing", just different details. Same ulimate outcome, though: less freedom for all, more power and control by government.
(bullhorn icon because it's kinda like a political stump speech)
