I probably won't be wearing one - I donated money to the cause (about £5 - so more than the cost of a poppy) but I don't want to wear one. For one thing, I don't think we need to wear one to show respect, and I choose to show respect in other ways, such as actually caring all year around, not just on the one day.
I also don't agree with the concept of just remembering British soldiers, as seems to be the norm - if I'm going to participate then I choose to remember everyone who has ever died in a way, whether they be on our side or not. I feel like wearing a poppy is too much of a British thing (which makes little sense, but hear me out). When we're confronted with atrocity, I think it's more important to remember that more than our own soldiers have died. Civilians die too, in the crossfire. We have blown countless Syrian families up.
So no, I won't be wearing a poppy, and I feel a bit dubious about giving money to the British Legion, even though I do to help the charity. That money does go to the army, in some form, and I don't want to be funding them at all. I may support those who have fallen, but I will never support our current army and the work they do. It's murder, pure and simple, whoever's on the other end of the gun.
