I agree but they cannot withold the parenting time unless a court order. Additionally, it's he says she says...is there a recording? Witnesses? Sometimes we can make things bigger than they are. Finally, step mom dictating to mom is not the most productive line to use...I know if a step dad tried telling me 1) I would be polite the 1st time, 2) then send a firm certified letter, then 3) whoop his as.
As far as your points, ok if they want to go to court and spend thousands over a he says she says good for them...I would say pick the battles more carefully.
