The Scot scored twice for victory over Everton on Saturday.
The Cherries have been branded 'naive' by pundits including Graeme Souness for being too attacking against the Premier League big-guns.
But Fraser said: “I have seen the pundits battering the gaffer and the club about playing too open but if that is the best you play and how to get the best out of your players why not play it?
“Nobody spoke about how we play then but got on our backs when we lost 4-0 to Liverpool.
“The gaffer and the players believe in this philosophy and that is all that matters. There is no right way of playing but that is what we believe in and it's a good way to succeed.
“We have been making mistakes but that is the way we play. We like to play our way out from the back and teams who are more direct do not make the same mistakes."
