Your statement tells me that you don't really have any idea what the words "leftist", "socialist", "Marxist", and "Communist" actually mean. I'd be willing to bet that you think they are synonymous.

Why not just leave the site and go join another one? I hear Trump has his own social media website now.

ok so what don't read them then

I truly believe it would help Immensely if you actually looked up the meanings of those "isms" you cite.

To develop your syllogism:

Major premise : Discount opinions here

Minor premise : You have an opinion

Conclusion : Ignore yourself

Dude. Seeing things differently is not wrong. Discount all you want , then why even engage discussion in all? That is when bad things happen. When people give up & resort to violence because of a kooky post on youtube.com. Me thinks you are posting in "general hellos" because the loyal opposition is blocked from any interaction with youz guyz in your groups. Too boring over at Slug? A discussion over there is if the government has the right to make zoophilia illegal. As long as its not a bat from the PRC.

It’s healthy to have access to - and to listen to a wide cross section of opinions on any issue from right across the spectrum….from the furthest extreme views on the right to the polar opposites on the extreme left. Only by doing so, can you understand where you yourself lie on that spectrum and whether in fact you lean to the left, right or are a confirmed centrist.

It’s unhealthy, not to mention unwise, to exclude or discount any opinions by any group because you perceive they are too anything…either too left or too right. That, in my opinion, merely indicates a closed mind, arrogance, and certainly not wisdom.

and nonbelievers and skeptics

Can't say I blame you, though I'm more than willing to ignore extremes of any sort. Neither extreme is genuinely liberal.

You left out humanist, realist, and non dogmatist!
