Unusual for me to be pointing out that there is middle ground, as I said above, namely: -
No banner on gate
No banner on marquee
No rules (apart from Folkmob constitution, if applicable) on personal apparel or caravan banners or displays.
Pete, I am not aware of Karen and Dal having had any input into the exchange about the Good Intent concert night, as you cite above. Nor am I aware of their having any applicable constitution that is in any way similar to the Folkmob constitution cited above, nor am I aware of there being any ban at the GI on t-shirts of any kind, although your position seems to have moved from opposition to a gate (or marquee) banner at Knockholt to opposition to antifascist apparel, or any other antifascist expression. In that you seem to go further than Mick's presentation of the "official line" (as above) that "a group of adults will not always agree".
