Honestly it sounds pretty unlikely that the anti-woke crowd would go after a random person writing Pokémon fanfic. Most of them are after attention and engagement; going after popular media gets them clicks and views and comments. If they wanted to go after 'woke' Pokémon fanfic, there are literally hundreds of thousands of Pokémon fics, so why would they go for any but some of the top five most popular in the fandom?
In general, negative attention can sound cool and like you could feel righteous about it in the abstract, but it's not actually any fun to be harassed by internet strangers, and I dearly hope you never have to experience that.
With regards to the general topic, I think a lot of it is, as Negrek brought up, that we're all adults these days with a lot of stuff going on in our lives other than reading fanfic. Communities have also moved into social media and real-time chats more than forums. Getting reviews is either a matter of posting on sites where there are a lot of readers - people who spend a lot of time reading fic as a hobby, who will tend to skew younger, etc. - or participating in communities in a reciprocal way. Review trades of various kinds are the most explicit way to get people to read your fic, but the other way is just befriending and forming connections with other people, showing interest in their work, and participating in community discussions in a way that might spark people's interest in what you're writing. When people don't have a huge amount of time for reading, they'll generally prioritize reading stories they've heard about that sound particularly interesting to them, or stories by people they like and have been having positive interactions with (including people who've read and reviewed their stories), not just something picked at random from the forum thread list.
Review events like Review Blitz are a good time for getting reviews, since while that's going on people will prioritize reading and reviewing more in their schedules for a bit - but it still tends to be the case that people pick which fics they read on the same basis: stories that have especially piqued their interest from what they've heard about them, or stories by people whose work they want to check out because they're friendly with and/or feel indebted to them, so community participation still tends to be key to getting reviews there. Blitz itself does have some themes that might give bonuses for certain types of fics, and now has a "heat bonus" that encourages reviewing people who have been putting out a lot of reviews for Blitz themselves - but that also comes back to participation.
All in all, outside of sites with a big surplus of readers compared to writers, you can't really expect to just drop your fic somewhere and have it get reviewed without any intention of reading other people's fics yourself - it goes without saying that if everyone thought like that, no one would ever review anything! So all in all, try to form connections and give back to others.
