Activism or merely tagging?

Does the caps 'E" mean it's more likely the latter as the campaigning group seem to brand themselves 'PeTA' these days.
Later on watched United v Partick on the telly. A celebratory game at Tannadice for the winning of the championship and promotion back to the SPL. Partick scored first, threatening to spoil the party but United equalised before half time and ended up 4-1 winners. Biggest crowd of the season with 11, 802 there - up to the sorts of crowd they get for a Dundee derby or an Old Firm visit. Still makes me wonder how they used to get 20000+ for the biggest European ties.
