Social media tends to give back what you put in. You'd be a fool to base opinions on that.
Argentina is also disliked in many countries so many people will want England to win for that reason alone.
Anyway, if you're going to do the usual coy thing and refuse to name all the countries you've (supposedly) visited, there's no point in continuing this line of conversation with you. I honestly couldn't give a toss what randomers in unnamed countries in 'Europe' (supposedly) say anyway.
