If you call yourself a periyarist:
Question everything, everyone
Demand answers
Instigate so hard like a pebble on the water, let the water be muddy
Don't worry it will hurt anyone, infact make them so uncomfortable
Stop afraid of brickbats, being sidelined, etc
Never be satisfied with mediocrity
Only pursuit of truth matters, nothing else
We are not here to massage anyone's ego
Presume worst and call out, let them come out with truth
Be a devil's advocate
No point in assuming good and keeping quiet, that's not our duty.
If necessary, make strong allegations when it looks and seems wrong or injustice or absurd
We don't have any personal interest other than truth, reason & public
Periyar is the greatest instigator / kalagakaarar
Otherwise, stop fooling yourself by identifying yourself as periyarist.
