I made this comment on Facebook a few weeks back, but I thought it was worth repeating here:

One thing that (many) social anarchists and (many) ancaps have in common is that they recognise anticapitalist individualist market anarchists as valuable comrades (albeit erring ones) as long as they’re dead 19th-century figures like Benjamin Tucker, Lysander Spooner, and Voltairine de Cleyre, and even include them in their favourite anthologies, but as soon as they encounter actual living 21st-century examples of anticapitalist individualist market anarchists, they cringe in horror and shriek either “capitalist!” or “commie!” depending on the direction of deviation.
