the dutch defence
It depends on the variation that you play. While there are at least 3 major variations that you can focus on (Classical, Stonewall, and Leningrad), I suggest focusing on 1-2 of the variations at the most in order to minimize the amount of work you put into the defense and be able to handle different positions when playing your pet variation is unfeasible. For example, I usually go for the Leningrad variation but there are times where it is safer to play Stonewall style positions.
If you respond to 1.d4 with 1...f5 at the club level, the majority of your games will be non mainline responses. So spend time on dealing with Anti-Dutch responses and anything similar to a London System or Colle System setups.
If you like playing the French Defense, one thing to strongly consider is to respond to 1.d4 with 1...e6.
Ultimately, it might not be the best for beginners but it is certainly not the worst choice. I suggest that you play through some games with strong players to familiarize yourself with the types of positions that you can expect before trying to play any new opening that you choose.

Is the dutch defence a great opening for bigenders against D4?
Totally fine for bigenders because in chess gender does not matter. If you meant beginners, then no.

I wouldn't say it's an opening for beginners because you really have to know what you're doing. 1..f5 has positional disadvantages - it's a non-developing move, blocks the light-squared bishop and weakens the kingside. All this is fine if you're familiar with Black's strategic ideas, but it's easy to get crushed if you#re a beginner. I'd recommend meeting 1.d4 with ...d5, intending a QGD.
