Which fanbase is worse? Doctor Who or Formula One?

There are quite a few other fandoms out there with the same problems....
I certainly know from my counter trolling offensives on my German fan forum and being a Star Trek fan....
At a guess, any fandom, no difference between sports and entertainment, harbours toxic people.
It has become worse lately.
MUCH worse.
In my German fandom, once upon a time until 10 years ago, the authors were hanging out with us on the forum and we had long and intense night time discussions.
I befriended one of the authors and got a ton of signed books and even a signed hand-drawn poster of the heroes.
It was absolutely fantastic and a fan's dream.
Fast forward to 2021, a few weeks ago, the latest audio came out, and features a gay couple. This is a series who had a trans character 20 years ago and it was no issue.
But now Pandora's box was opened with this and no moderators in sight to put the lid back on. The author came onto the forum to defend himself, and was insulted very very badly.
I felt so ashamed for these trolls.
Last week, I had time on my hands and entertained myself with a counter trolling offensive and pulled the legs of these trolls by posing on the forum as "a woke socialist SJW fascist" (obviously with split personality). I was glorious. Especially, since I was told how bad gay parents are for child care, and then one of the guys completely unrelated started on telling me how casting a woman as the Doctor destroyed Doctor Who. On a completely unrelated German forum. Now, THAT set me off. It was like Christmas for me. My put down was glorious.
The guy later admitted that he had never seen Doctor Who in his life and just heard about it and the evil woman on the interwebs.
Point made.
I rest my case.

But yeah, I am shocked how much fandom in general has devolved into a mud-flinging contest among primitive cave trolls recently.
In the year 2021!!!
I would not have foreseen this 10 years ago if I am honest.

Doctor Who. The majority of fans are & have always been rude entitled arseholes who hate any version of the show that doesn't fit their particular needs

Now, if we're going into the broader question of 'why have fandoms become more unpleasant/toxic places in the last decade', there's a series on Youtube by Innuedo Studios called The Alt Right Playbook, which talks about how 'normal people' can become radicalized in an online space and how that relates to the state of modern politics and fandoms (there's a couple devoted to 'the event' in gaming which had a big influence on what has happened since in other places, like the NMDs).

Star Wars/Star Trek/Doctor Who. some of the most "passionate" fans..

No one has mentioned "Bronies"?

Music fans are the absolute worst, verbally.
Genre fans make the online world very trying.
Sports fans are the most reactive, physically.

Any fandom has its minority clique of rabid extremists.
All the way from the ' My Supreme Deity is the Best and I Know What It's Thinking' afficionadoes to the 'Only Wear Brown Shoes with Brown Suits' brigade...

yup!.. They are the template for "bottom of the barrel"..  

Yes they are not toxic like a lot of doctor who fans on social media & forums. Nasty people with their petty bias & vendettas. I think a lot of them want the show to be cancelled.
