As activists in Cork will know, Brian Wallace/David Noone and his motley and tiny assortment of holocaust deniers have been postering the city with their "holocaust did not happen" posters. It goes without saying that these posters (and that associated racist stickers) have not lasted long on the lampposts.
There are now new posters, in German - I think they say "Wahrheit der Deutschland" or something of the sort and advertise a few websites. My German is limited but 'Wahrheit' means 'Truth' or 'Lowdown' and one of the websites (the only one I checked) is that of David Irving.
So tear them down!
