Am I a bad person because I choose which animal in nature I want to feed?

There are all sorts of critters in our backyard, gophers, chipmunks, rabbits, raccoons, skunks, and squirrels that come in grey, black and red. We also have garter snakes and toads. Moles, voles and rats as well. And of course, we also have birds. At certain times of the day, the bird traffic resembles the streaks of red or white light of cars on roads, streaks of yellow, brown and red darting from tree to tree with the accompanying squawking, chirping and tweeting.All creatures deserving of food.
The squirrels, cute as they may be, really are a major nuisance. At this time of the year, they gather their nuts. Their preferred method is to
climb to the top of the oak trees, snip off tender shoots with leaves and acorn and drop them to the ground, where the acorn shell breaks and the meat is easily and readily accessible. Clever and destructive.

Our cars have been completely dented, our driveway looks like it has a carpet of broken brown shards. All this to say that there many of THEM around, and only two of US. And they are winning: they chase the birds away, they destroy our bulbs, they destroy our cars. So when it came to time to buy a bird feeder, it had to absolutely be squirrel proof. And so we bought one and to our delight and amusement, the squirrels would find the “door shut” as they clung to the feeder or jumped on it, their weight doing the trick. So we enjoyed the birds comings and goings until the chipmunk and red squirrels entered the scene. They are light, they are quick and they are clever.
The squirrel proof feeder is no longer a sanctuary for the birds. The weight of the lesser squirrel like creatures is not enough to lower the “door” to the seeds. So you can see them perched with their snouts in the hole, filling their cheeks full of seeds. So we devised some contraption to keep them away. It is working for now. But as I said before, they are clever and it is just a question of time.
I really do not want to feed THEM. I want to feed the birds. Am I a bad person for segregating, favouring and supporting who I want to feed in the wild?
