I've been on too many threads with Tan, and tried too often to get an answer to a straightforward question...
I don't have a problem having conversations with people I disagree with. I do have a problem with people who cherrypick half a sentence out of a long post and decide that's the thing they're going to respond to.
It's all very Nick Clegg circa 2010 "I'm going to reframe your question and answer the question you should have asked me that will allow me to get my talking points across"
I'm pretty easygoing, but my patience is not infinite.
