Similarly people who champion the removal of animal products but won’t look into the eyes of a combine harvester and the animal it has ran over, the displacement or slaughter of animals in the clearing of farmlands, the increase in water consumption as new areas are turned over to fast cash crop agriculture based on whatever the current trend is,

Animal products require the cultivation of more plants than vegan food. Animals need to be fed, and they burn tons of calories to stay alive.

the removal of byproducts from industry such as long lasting leathers of adhesive products in exchange for quick rotting fast fashion made largely of petroleum products, and the costs associated with all of that are also misguided at best to delusional at worst.

Without subsidies, it is cheaper to make long-lasting bioplastics from plant matter than to raise a cow and kill it for its skin. The fashion industry makes clothes that decay in order to sell more clothes, and the meat industry artificially lowers the price of leather.

So maybe instead of fighting one another over petty concerns we can come together and take a look at the system trying to keep people apart and reliant on its own monstrous excess

Agreed, you should take a look at the system and let go of your petty concerns. This will make you vegan.
