Well, he probably asked you for sexist reasons, that you were a girl, but it isn't all bad.
Writing the minutes is an opportunity I would encourage you to prepare for, and grasp with both hands.
In that situation, I would say that i was happy to minute the decision and action points (rather than capturing everything everyone bored on about for hours...). Once that is agreed, it gives you the power in the meeting, to ask for clarification of 'what action has been agreed' or 'what have we actually decided'. You are ostensibly asking for a one line summary for the minutes. If the action is clear, you can say 'so we have decided that the Christmas party will be held on and be organised by rather than ask what has been decided.
More often the discussion has just petered out, with everyone thinking their point has been the one that is agreed. When someone asks for clarification , if everyone says something different, well you have got them to see that they haven't yet really got a decision. Whatever you say is the action will be it, unless someone disagrees.
If it is too complicated for you to capture/understand, catch the eye of whoever sounds confident or whoevers version you want to have happen and ask them (just a glance will do it, you are telling really) that you will check the details with them afterwards.
Writing the minutes is a very, very useful job. It is not uncommon for people to forget from one meeting to the next what actually happened. The person who writes the minutes to an extent decides what the record shows happened in the meeting, so within limits, you can emphasise things close to your heart and de-emphasise this you don't agree with.
The first couple of times you do it, especially in an area at you don't understand too well, it's always good to arrange for someone to review what you have produced , maybe the chair or someone nominated by the chair, in order to avoid any howlers.
It becomes a lot easier with practise, it also means that you are fully engaged in the meeting and build an understanding of what is going on. You have shown yourself to be very useful and you have become part of the management team. This is a platform that you can exploit. If discussion is getting bogged down, you can say 'shall we take this off line with x and y' and then, you are having a meeting with x & y and getting them to sort something out. You are also providing the record of what happened back to the meeting for their approval.
Meetings which are run focused in decisions and actions work much better, are done. More quickly and hence much more popular with people. People who otherwise might have tried to get out of it, will be prepared to give their expertise.
You will find yourself known by name by more senior people, who might then fight to have you included in whatever they do. This is especially important in larger organisations, where building your network is so important.
And if the chair doesn't like the decisions and actions only approach, you know to keep a wide birth in future. Maybe track his secretary's schedule and turn up a tad late anytime she is likely to be away.
It certainly worked for my career, all the best.
