Are you sensitive to having your ideas challenged?
Do you like to hear other perspectives?
Does it feel like arguing or comrade re when someone disagrees?
Does debate feel like an attack- or an act of respect (that someone would value you enough to bother)?
In order to know and grow one has to get involved in non-judgemental, rational talk. I find I often learn as much as another when sharing information.
I'm an open book but you might be offended by my answer so make sure you are before you ask.
