Ben,
Not illegal to flyer outside, every attendant, with this revealing admission 'bitcoin is only for those who have opinions we agree with'. Pointing out the ironic hypocrisy of the organisers.
Also, write the local papers & press release the crypto-news outlets, requesting people don't attend this CENSORED conference (so much for believing in censorship resistant money).
Thanks for outing these shysters.
I haven't read your timeline to check for 'direct anti-semitism' ... I took this to be accurate, from someone who did:
Stick to your truths.
