It's really really petty and ugly. WP should be talking about fixing the PAP, not the SDP. And if they want to continue chatting, it's up to them.
There is a glaring absence in terms of the WP rank and file discussing national issues. Almost everything is local politics. It's almost as though only the leadership were dealing with the national issues, if at all. This is not how a democracy should work.
They do table many questions dealing with national issues. Maybe it just the way they ask questions wasn't confrontational enough for your likings?
