Hi Dennis,
Even though I can only speak for myself, I don't see any problems with you joining us since you understand about the need for proper procedure.
Oh, I used to feel just like you about not shooting someone in a parachute. That is until I was shot down a few times by folks in parachutes. I now can also claim numerous kills from my own parachute. Which is only resonable seeing as how much time I spend in parachutes!

The only time I will shoot someone on a runway is if I am coming in for bombing run or to help cover for my teammates coming in for bombing run. Again, I learned this the hard way after having my butt shot off by respawned enemy just I was ever so close to that enemy hanger. Now, low life, spawnkilling tanks are a whole different story.

I make darned sure I make mental note of these vermin so that I can single them out in future games to perpetually give them hell from now on until they decide to change their ways.
I do not typically shoot anyone sitting on carrier deck. Or, in a dogfight free for all when they are going in for a landing to reload. I just can't bring myself to do that even though I get shot lots of times when I try to reload. And same thing applies when other pilots are attempting to take off. I do not shoot at them intil they are airborne and can defend themselves, even though this has cost me dearly at times.

EDITED TO ADD; Also, if you do not shoot parachute, you most likely will have a tank to deal with. This can be extremely disasterous if they make it to your base and destroy your hangers.
