Being a TD must be one of the most family friendly jobs in Ireland. Short working week, short days, long holidays etc etc. And not even required to attend the Dail except for important votes. Would be difficult to make it more accommodating.
Any TD who tried this won't get re-elected. The average TD will find themselves attending 1 or 2 residents/campaign meetings a week, maybe 1 or 2 meetings of their own party branches, and will be running clinics for constituents as well.
There is a well-established approach in equality circles of 'positive action'. For example, you may need to provide an sign-language interpreter for a deaf person attending an event. This is not 'equality', but is providing equal access. You may need to provide extra language teachers for kids for whom English is not their first language at home, to ensure that they catch up on their classmates. This is not 'equality', but is providing equal access.
Similarly, there are barriers for many people in participating in politics. Some of these barriers can be addressed by providing extra supports, and some will need infrastructural changes.
It is disappointing that for many people, 'equality' is narrowed down to gender equality, and gender equality is narrowed down to wimmin's issues. I don't believe that quotas are the answer to this problem.
