Challenge someone's previous statement and point out flawed reasoning or factual inaccuracies. Then, question the relevance of portraying the Taliban as proponents of left-wing values.
Lots of ignorance in your post...but..
The Taliban refused to hand over any Al-Qaeda suspects including Bin Laden. They called Al-Qaeda their brothers in arms. And since when are the Taliban heroes of left-wing values? Go ask for their views on women.
