So what you are arguing is essentially 'if you are not with us, you are against the terrorists?'
The only reason that strategy sometimes works (and it does by no means work in all cases, just see what happened to Pompey the Great when he tried it) is that there is some kind of punishment for those who are against you.
If you want to win people over, don't be combative. Stand firm on your belief but hand over olive branch after olive branch -- people that will give people plenty of opertunities to change their minds and will leave a favourable impression, which will be useful later.
What you have just done is the opposite of helping your cause.
