The Lions Cave

It/they and any neos collectively

[popmusiccollective]

Intro!!

Hello!! We are the Pop Music Collective; a recently discovered mixed conscience modular system! We use they/it and neopronouns collectively, although I (Syd, the host) only use it/its and neos. I’ll also probably be the one posting the most often, since I’m frontstuck.

I basically created this blog to re/post stuff on alterhumans/therians/nonhumans as well as some system/plural things!!

Here’s my cardd! (Lmk if/how I can improve it, first time making one lol)

shoutout to endogenic systems!

shoutout to endogenic systems who used to be anti-endo!

shoutout to endogenic systems who always new they were endogenic!

shoutout to endogenic systems who were traumatized by people harassing them over their origin!

[positivitygenic]

as a headmate, your boundaries around what topics you wish to engage in deserve to be respected. you and your system knows what is most appropriate and most helpful for you. not everyone experiences age the same way, that is absolutely fine and a known fact that systemhood is sometimes intertwined with. you have a right to be respected as who you are, and not what onlookers believe you should be.

Always remember;

There is nothing inherently wrong with being plural.

There is nothing inherently wrong with wanting to be plural.

There is no wrong way to be plural.

Plurality is a framework and concept, no one owns it no matter what they scream their little heads off about.

Traumagenic plurality is beautiful.

Nontraumagenic plurality is beautiful.

Created plurality is beautiful.

Every plurals existence is important and part of something beautiful, be it survivorship, companionship, creativity or even spite.

The future is plural, and will always be.

You& exist and always will.

[thisis-speciesism]

everytime i see a post that makes a good point on a certain topic it always implies being human is what makes you worthy of respect or something like that

"aplatonics are human too we deserve respect" oh guess im an asshole for being an aplatonic seagull. i know this is more likely kinmisia but those posts imply humans are somehow more special and deserve more respect than nonhumans (theriform or not) so yeah it pisses me off

This is speciesism and alterhumisia.

As another nonhuman alterhuman, I ✨also✨ fucking hate this shit.

PSA: DO NOT USE FLORALITY. THEY THINK THAT ENDOGENIC SYSTEMS ARE DELUSIONS, WHICH IS LITERALLY BIGOTED NOT ONLY TO PEOPLE WITH SPIRITUAL AND OTHERWISE NON-TRAUMA PLURALITY, BUT TO PEOPLE WITH ACTUAL PSYCHOSIS. WHAT THE FUCK?

how it feels trying to hold back the mean alters from saying mean shit
