You did ask for the debate to stop or not even be allowed to start on a thread about a terrorist incident Elegran - and you are still wanting your opinion to be agreed with, you still want to be told you are right when there is no right or wrong. Deciding when to start talking about the political aspect of this will be for each person to decide for themselves.
I chose to comment on my sadness about the horrible attack right at the beginning of the thread, around the eighth post, and by that time someone had ALREADY made an anti-corbyn post. I commented then that is was a little out of place but it didn't stop. If you are not aware you are being political, as you appear not to be, it may be that you are actually encouraging threads to move to the political.
No one is being shouted down. That sounds just like a small child who cannot win an argument. I just disagree with you and have been happy to provide an argument that shows why I think you are wrong to try and impose your views. That is how discussion works. You are really on a hiding to nothing on a forum if you always believe your opinions are a fact just because they are YOUR opinions and if it is not a fact then we may each make up our own minds without others telling us when a subject should have it political aspects discussed.
