an anarchist telling someone they are not an anarchist because of small issues is generally frowned upon by other anarchists (nobody’s perfect), but they will allow it if an individual repeatedly acts in a coercive and/or authoritarian way.
In theory.
In practice they take a very dim view of fascists coming round to visit, and the London Anarchist Bookfair has repeatedly refused to let the SPGB have a stall, even though the only major difference of opinion between the two is whether you should vote or not. The LIbertarian Alliance were once thrown out for hijacking a stall and selling pro-capitalist books.
Again, don’t act in a coercive or authoritarian manner and you will be welcome. Allowing abusive behavior causes problems, see the fallout from this years London Anarchist bookfair after TERFs were allowed* to hand out leaflets outside the toilets
* They weren’t invited, but none of the organisers stopped them at least initially. Now imagine how quickly they would have been kicked out if they were handing out anti-immigrant leaflets instead of anti-trans.
