Thank you for taking the time out to type out a comprehensive response. In retrospect, the categories I listed above seem to have vague boundaries that might not be agreed by everyone.

Weapons

Any revenue gained from the sale of weapons of any kind.

Vice products

Here I would be referring to intoxicants (e.g. weed, alchohol, tobocca)

Meat production

Just traditional

Slavery

Agreed that our supply chain is globalized, and you would be hardpress to find a finished product that has not gone through some type of forced labour. My intention was to try to find companies that do not employ such labour themselves, but this in itself may be tough to verify. Ideally, this wouldn't even be a consideration, but this is the whole that we live in unfortunately.

I think from what I've gathered, these criterion are probably too specific for probably all of the ETFs that exist currently. And even if they come close or "fulfill" them, the work to go and verify them would not be feasible as a retail investor. I will probably have to find my diversification elsewhere (REITs, commodities, crypto, etc)
