I would rither write in your profile that you don’t plan to respond if you feel it isn’t a match or tell the person nicely that you are not interested. No matter what, you’ll always be wrong in someone’s eyes so don’t stress over it.
I dated a 46 yr old when I was 29 and many aspects where great. I would have married her if it weren't for certain circumstances but there are a few small drawbacks.
