Is there any website that I can create a Politics group?

You found wordpress.com, and could use that, free.  Or another blogging platform, say, blogger.com .  Why not start there?  It might be justme_ria.wordpress.com to start off, but should be accessible to the public.  From that, you can learn the ins and outs of administering a site.

A domain doesn't cost much, especially if you go with one of the less popular extensions, like .xyz or .club .  If you shop, you can probably find something for $10 a year, $20 tops.  I got 10 years for $50, but that was an intro deal many years ago.

I am also looking for a good and free one for my blog. The current one i am having right now is not helping.

My blog is just about anything.

It's called "Wordpress", and creating a blog on wordpress.com is free unless you absolutely must have your own domain.

If you are fine with a subdomain like freezepeach.wordpress.com, then go ahead.

However, free wordpress is primarily for blogs or portfolios. It sounds like what you want is more like Discord, which is also free.

https://discord.com/

Try proboards.com. It's free and you can be the administrator of your own forum.

You can create a "group" in just about 

any social media, you don't need a full 

website. There is Facebook, MeWe, 

Parler, Nextdoor, Quora, Skyrock, Vk, 

... literally hundreds more. 

FACEBOOK.   You can use FB in lieu of a Web Page.
