I shall continue to use generalise , apologise, organise, recognise, empathise, analyse, and all other -ises and -yses, since those are the correct spellings in English, the language used in England where English originated from.Travelled has 2 L's, Manoeuvre has an O, Defence has a c, as does Offence, Licence, etc.Colour has a U, as does Flavour, Labour, Neighbour, and of course Humour If you choose to spell it differently in "simplified" American English, then that is of course your choice.
Actually, I rather enjoy seeing the correct spellings once in awhile...
Amazingly; When I attached your note, Spell Check said that all the words you listed, are spelled wrong...
