Is it me? Am I being sensitive? Am I a disgruntled traveler?

On a two short flights today (MHT->BWI and BWI->EWR), which are 60min and 35min respectively. I sat behind two folks how felt the need to jam their seat into my knees. On one of the flights I was in the 2nd row aisle and the person in row 1, with plenty of leg room, jammed her seat into me. I have to say, I am 6'2" and my knees almost hit the seat when it's not reclined.

This leads to the question, is reclining your seat back a "no no" like I think perceive it to be? Especially on short flights.

Personally, though I would like to, I never recline my seat unless no one is behind me. If I did, I would look at the person I am about to flatten and ask if they mind if I recline my seat. I would also gauge the person's leg room as I did this and not even attempt it if they were using a laptop or were tall.

Am I being sensitive about this?

I was about the smack the lady upside the head in front of me who seemed to get an extra 2-3 inches past the typical reclined position. THat pushed me over the edge.
