Interesting question and I trust the motivation in asking it is sincere, will give the benefit of the doubt anyway.
I am 64 years old and joined
FF 32 years ago. Though fathers family were very republican politics was very rarely mentioned. I knew father as a child was used to move guns from one place to another and his father had been viciously beaten up by the Black & Tans. Also, fathers first cousin was the first to be killed in action on the day the Civil War started. Despite this I can honestly say there was never a trace of pressure to vote
FF in my first 32 years. To me its a personality thing and difficult to explain. As you probably know
FF sees itself as a "movement" and not a party in the normal sense. Have never met a
FF member with what is called an ideology, its like saying simply that someone has to run the country and we are the people who want to do that cause someone has to do it. The word pragmatism is regulary thrown at
FF and like all words with ism it allows freedom of the mind to juggle with those who disagree.
FF is also seen as a populist party and there is plenty of truth in that also.
Will fiinish this off in a second post as I am not too good at typing and time runs out if you are slow on this site
