Yeah, I tend to agree. There's conditions to everything. The point, though, is that when those conditions include privately held beliefs/morals or things done in private that don't impact the other party in any way, that's someone attempting to enforce an undue level of control over your life. It's just easier to call it unconditional love than to go into all the ins and outs.
One other difference is that many people (though they may not get there immediately) can still find it within themselves to wish another person well even after ending a friendship due to being wronged. Even if they no longer wish to pursue the relationship, they can forgive and forget. That, to me, is the only version of unconditional love that can really be said to exist. And much of the time it's wholly absent in JWs. I've heard the most vitriolic slander spoken about people merely because they no longer attend meetings. They haven't even wronged anyone in any way, they simply don't believe it. Yet they are spoken against and many JWs will miss no opportunity to make their life more difficult.
I get it that when people don't see someone twice a week, their friendship is probably going to drop off and not be as close. People lose touch. That's fine. When people are suggesting that simply because you're not around you're lying, cheating on your spouse, stealing or (honestly, I've heard all of these said about apostates by their family members, and the only justification given was their apostasy) plotting to purchase a bunch of guns and shoot up a kingdom hall - that's the sort of stuff that crosses the line. The fact that most JWs are mentally prepared to treat you like you don't exist merely for failure to believe the insane claims of 7 men in NY demonstrates that not only do they not show unconditional love, but that they don't really love to begin with.
