Pub Def has coverage of the ongoing sit in.

Maybe you can find some names to heckle there.

Seems to me you have been connected to gathering and organizing people for the sole purpose of deliberately heckling and ruining other people's events, yet you take offense when a little friendly heckling is directed at you. So how does it feel?
For as long as you continue to interfere with others, you can expect to receive the same. Otherwise, can we declare a truce?
