lol I'm not surprised at the tone. From the beginning of learning to play poker the primary message is play TAGG, if you're going to play a hand play it aggressively, if you play aggressively you can win at showdown or win by getting them to fold etc etc. But there's a time and a place for everything.

There are several reasons to play passively:
-We keep worse hands in, and allow them to bluff
-We control the size of the pot
-We balance with other parts of our range
These to name a few.

Thinking that every strong hand has to be played aggressively in every spot will result in taking the less than ideal line fairly often.

Balance is probably the biggest reason for passive lines. Though balance may not be critical at lower stakes it's important to think about. How are you playing AA/QQ pre? I'm assuming 4betting. I'm assuming you're probably not playing KT to a 3b. So your credible value range on this flop is AQ and JJ, and I'd say only half of AJ combos should raise (4) and QJ should c/c down as well, so 16 combos. If we also see flop with maybe some AK given stacks? (2), KQs (3), KJs (3), ATs(3), JTs (3), some A7-A9s? (9) - so about 23 combos that will c/c the flop. Of these 23 combos a TON of these combos I'd argue can't take much more heat. You really need a hand like ATcc in your range that can face barrels here. This is also why I say not to raise half of AJ or QJ on flop, so we have more hands here to c/c down with.

-taking a passive line isn't always a bad thing
