I think the problem here is mainly with the creationist habit of misusing 19th Century terminology like 'Catrostophism/Gradualism' and yes, micro/macro-evolution. They really need to do at least their minimal prerequisit research before beginning a debate though if they did so they wouldn't be creationists.
By definition the first rung of the macro-evolutionary ladder is speciation which, if anyone would care to look into it, is an observable phenomenon both indirectly and directly so the old creationist cannon that there's some magical wall keeping evolution proceeding from the formations of breeds within species to new species is nonsense to begin with.
Cheers.

democrats are sometimes inept and presently lost but republicans are mean scientifically ignorant hypocrites, I know what lesser of two evils is the most rational choice.
