Supports what?
If a woman were to stand up in the middle of a service and say "I feel led to take over this service, stop preaching" or "I feel led to take over this church, let me have your seat" that would be snatching authority from a man; undermining his authority, humiliating him. Maybe the church that you go to allows for that possibility - that anyone who feels led to lead/preach can do so on the spot.
That is not the case - even in churches which have female preachers and clergy.
You don't seem to realise that the process of selection for ordination is a long one - and involves many other people.
In my church (UK Methodist) a person cannot be ordained without first becoming a Local Preacher. That involves interviews, academic study, assessed services- and lots of prayer. IF a trainee preacher passes everything and they, the congregations and the other preachers are satisfied, they will eventually be accredited/licensed. All this can take up to 5 years - longer, if there are extenuating circumstances. Only after a person becomes a preacher can they then begin to think about ordination, (at least, they may think about it sooner but they have to be licensed before their application will be accepted.)
The process for ordination may last a year or 18 months - the candidate has to produce a portfolio and do various other pieces of work. When it's completed they will go before the Circuit meeting who vote on whether or not to support their application. Even if everyone voted against them they could still go onto the next stage, but the first question would be "why don't your circuit support you?" The second stage is the District Candidates Committee, at which they may, or may not, be recommended. If they ARE recommended they do it all over again but with clergy from all over the country.
If a candidate gets through all that they go to college for 2 years.
If they survive college they become a Probation Minister for 2 years - unless they are having problems/are not very good in which case they may either be given time to improve or it will be suggested they are not in the right ministry.
If they survive all that, and they, the clergy and the congregations are happy, THEN they will be ordained.
A call is tested, tested and tested again - all this involves other people, prayer, discussion, study and more prayer. It involves male clergy who interview, assess, pray with, teach, mentor and train candidates, and congregations, who are more than capable of saying if they think an ordinand is "in the wrong job". In fact, at the ordination, the church is asked if they will accept that person's ministry.
Now how is any of that violently snatching authority from anyone?
If a trainee preacher/ordinand does not have support from other people, they won't get through.
