In reply to owlart:
Your post tries to equate 3 quite separate issues:
1) A personal act of remembrance, which may (or may not) include wearing a visible token, attending a parade/ cenotaph/ religious ceremony, silences, private reflection etc.
2) A charitable donation of money, goods or time to service charities / RBL/ peace charities etc.
3) Virtue signalling by being seen to purchase merchandise / "this season's poppy".
