“These toys can have a negative effect on children. They can destroy their souls and lead them to the dark side” Polish priest Slawomir Kostrzewa told the UK Telegraph recently. They're the work of the devil! Much as My Little Pony toys are really the "carrier of death."
I know you're looking at the date of my post and thinking I'm making it all up, but no such luck. Apparently this is not a hilarious April Fool's joke like the "I'm hiding in the bathroom during a massive college campus shooting" prank this chick tried to pull off. (Hint: it doesn't end well.)
I do think some of the LEGO products are a little overly-dark for small children, however. And I would allow my older children to collect and construct BIONICLE items, but not to watch the movies and read the books while they were smaller. There's a whole fake theology and storyline connected with them that I don't appreciate.
I don't really want to devise motives for Satan, but I'm just guessing LEGO is not number one on his list.
