It is not supposed to be competitive, although I know it can be enjoyed that way, and the rare trans woman identifying as female and having first finishes or course records would be annoying. But for the vast majority of us it is about PBs, ‘ridiculous’ challenges (as someone called them above - personally think they are fun) and mostly community.
If parkrun wants to be inclusive, is not competitive and is only about personal bests, then presumably they only tell people their own times.
That's not the case though, is it?
Copied from their homepage:
Female record: Charlotte ARTER – 15:49 ( 1 Feb 2020)
Male record: Andrew BADDELEY – 13:48 (11 Aug 2012)
Age graded record: Fauja SINGH - 179.04% 38:34 (31 Mar 2012)
And this list of male and female first finishers:

It's not okay to allow men to take women's places and pretend that's fair.
