'I am entitled to support any team I wish, and no long winded post will change my mind'

So, with regards to your words, you are a Real Madrid supporter.

Of course, every person is free to support any team he or she wishes, especially in our English society.

By the way, the adjective 'long-winded' is used to express an individual's opinion of something they have seen or heard and it is commonly used to express a negative opinion. It is possible, some people think in a totally different way to you.
I did not set out to change your mind.
