I thought the protest was against Theresa May getting into bed with the DUP, especially after all the criticism Corbyn received for talking to the IRA years ago, and about austerity - which looks as though it has directly led to major loss of life in the most appalling fashion.
Ideally I would like our Government to have compassion and regard for the whole population instead of being self-serving, money grubbing and only interested in the wealthy, and if we have to protest to make them realise, I am all for it. No one yet has stopped May from forming a Government, apart from herself, so I fail to see why this is anti-democracy.
