Hang on a minute. The implication/assumption seems to be that Robinson was sacked, set up a fund for donations which he them spends on an expensive holiday.
A more likely assumption would be he booked and paid for said holiday whilst still employed. To cancel it on losing his job in the last few days would entail losing all or most of what he had paid.
He recently received an out of court settlement of £8000 from the Royal Academy of Dancing who 'cancelled' him for questioning drag artists reading to children.
He may also have set up his fund to enable those who wish to support him, especially evangelical Anglicans, to be able to do so. There is precedent for this - Rev Brett Murphy recently left the C of E to start a new Free Anglican church from scratch due to the apostasy of its current bishops, and was inundated with offers of help to finance it whilst it grew from its initial congregation of two!
If Robinson has used any of the donations on the cost of his holiday I think he has been foolish, but in the end is it anyone else's business?
