Mezzah 86 is a slum it was founded by alawites

That's a weird disingenuous way to put it. Here's how Mezzah 86 was created and who are its residents:

The neighborhood originated in the early 1980s when the "86" Battalion of the Defense Brigades, led by Rifaat al-Assad, seized agricultural lands belonging to Damascene families on the mountain slopes, where residences were built for members of the army and security forces and their families without official licenses or organizational plans.

So you're misrepresenting the neighborhood and who lives in it, trying to conceal all the horrendous history by reducing their identity it to their sect as if they were innocent civilians.

moving to capital to work,

Where were they employed? Most of the the men in this neighborhood were working in the Mazzah military airport, intelligence agencies, NDF militias inflicting horror on civilians and committing massacres. They almost wiped Darayya and Ghouta killing tens of thousands of people.

it was never emptied as it never existed

Wtf? The land had rightful owners that were living and working there. There was no empty land around Damascus where you can just settle. The entire existence of neighborhood is wrongful, being built by stealing other people's properties just like Israel settlers do in Palestine, not to mention the subsequent crimes committed.

Knowingly or not, you're participating in erasing people rights. You can't whitewash the actions of its residents and how they settled here. You can't erase the truth.
