How do you feel about muslims praying on the grounds of westminster abbey, what motivation could be behind such an act

Don't they have their own mosques? I find is quite rude... they stop poxy trafix for their praying but when christian people wants to organise fun day in the park government refuses bcse 'its forcing others with yr religion' so I m totally opose muslim using Westminster Abbey grounds for their prayers .... they can do that in the own homes... praying is not for SHOW... DO IT FOR YOURSELF! this footage pissed me off... what exactly do they wanna show with praying outside W A??? ....
