Indeed. This type of behavior only makes sense if defending trademarks never incurs a penalty when it gets overly aggressive.

I will avoid buying anything at backcountry.com (unless I forget, which hopefully I won't), so I guess that's a bit of a penalty this time.

I won't forget; I've looked at them before when comparison shopping certain more-expensive items at REI.

I'll just use REI now; they don't seem to sue people (plus, REI isn't a common word anyway), they have a fantastic return policy I've used a couple times now, and I get 10% back for being a member, plus various coupons throughout the year.
