Here too on REI. I've been a member for probably over 30 years and spent a lot of money in their stores and online. I've physically made purchases in REI stores in at least 5 different states. I even have an REI Credit Card. No more, canceling membership, CC, and will not buy from them again. I emailed the board to let them know too. I think they will be surprised by the number of gun owners that also are outdoor enthusiasts (rock climbing, mountain biking, hiking, backpacking, etc.) that previously shopped at and supported REI.
Even more than gun owners. They definitely seem to be targeting a particular customer base more than ever in recent years, as can be seen by their stance in Utah. Which I guess is fine. They will lose some customers and gain others.
I don't mind shopping at a store known as liberal, but I just won't shop at a store that is actively liberal. If the owner/corporation has different political viewpoints than me, I can generally live with that. When they say they hate me and don't want me in their stores, well, to paraphrase, "It's not me, it's you."
