Alright, third point:

I don't think contraception is inherently bad, and I think that Catholics implicitly admit as much in their use of Natural Family Planning (in that they can conceive of a sex act designed to avoid contraception).

What's wrong is not contraception, but rather the contraceptive mentality. It is this distinction that justifies NFP in the first place.

Even though NFP is technically more reliable as a contraceptive practice than physical or hormonal practices (if I'm not mistaken), those using NFP rather than prophylactics have very different thoughts going through their minds.

A cultural attitude has grown around condoms and the like which encourages people to think "Hey, this is sex with no consequences." Even though the possibility of pregnancy is very real in fact, it doesn't seem to be on the minds of those using the condom (which explains the incredibly shock and dismay that results when said condom doesn't do its job).

If a couple using NFP gets pregnant, though, you won't get the "Damn, I'm a father!" response. Though it is an approach designed to avoid contraception, the couple engaging in it is simply realizing "There is an aspect of sex apart from contraception. It is only one aspect though. Despite the fact that we'd prefer to avoid having children at this time, we still want children and will embrace one should we inadvertently conceive."

This is subtle, I know, and perhaps I'm not explaining it well. If so, I apologize. But the attitude behind NFP is the sort of attitude the Orthodox want behind use of contraception (which is allowed only for a married couple, of course). The culture has attached the contraceptive mentality to contraceptives so there is a very real danger of an Orthodox couple approaching the process the wrong way, though I think a Catholic couple could approach NFP the wrong way just as easily.
