If you found out a man had been a member of PIE (Paedophile Information Exchange if you didn't know which was a legitimate organisation in the public domain with the backing of several prominent mps arguing to lower the age of consent/ make paedophilia socially acceptable) but appeared respectable now with a high up job, and had apologised for being a member, claiming he didn't understand what it was or he was just 'networking' would you still be highly suspicious of them and question their motives for everything? Yanbu - man is most likely a paedophile
Yabu - it was a long time ago, he didn't know what he was doing
