I hope you accept that “we” here represents a minority view in Islam.

. Nothing wrong with a minority view and it helps people to understand Islam is not monolithic.
For me, Aisha’s age at marriage and consummation, whatever they are, is not an issue or the issue. We should not be judging people in the past by standards we hold today. If we do so, all of past humanity would be guilty of a multitude of sins as few in history can escape practices of torture, murder, homophobia, sexism, racism, slavery, ageism, etc etc etc. Stating that someone’s practice as a historical fact is fine if we are just differentiating what he/she did is not what we would do today. That is just historical fact.
My issue is with taking the historical fact (however it is arrived at) out of the context of the day and apply it to today’s world without regards to differing context. Thus, to say that if it is fine for Mohammad to marry a girl of 7 in his day means that it is fine to do so today - that to me ignores that context of culture, values & knowledge that informs moral judgement today in a way that it would be different for a different context in the past.
Which is the main problem for mainstream Muslims today. Taking a literalist interpretation of scriptures of any type (divine or human, meaning Quran or Hadith/Sunna) and ignoring social and historical human context usually means application of norms that may not be appropriate for the contemporary society even if it was appropriate for a society long disappeared. This has led to Muslim approval of child marriages, among other social ills.
It is interesting that to stay within the context of such a literalist thinking that arrived at a conclusion at odds with modern day values (Mohammad’s action would have been illegal in many countries today), some Muslims subscribe to an alternative interpretation of facts which allows the actions of Mohammad to be consistent with social norms of today, namely that Aisha was of age (by today’s laws) when she married Mohammad. That remains a minority view and to me, unnecessary if the intention is to reconcile Mohammad’s actions with norms of today. Mohammad did what he did because of the context of his days and we do what we do today because of the context of our day. What counts is not the action (a literalist view) but the purity of the intention (an interpretive view).
In that sense, I would disagree with the purity of intention as his marriage is not out of love for the person but for personal gain - the political ends. Even if one were to say he did it for God, it would mean that furthering God’s kingdom takes precedence over someone’s freedom to choose one’s life partner in an informed manner - Aisha had no choice as even her own account did not refer to any opinion of her own at that age. Having said that, I understand that such marriage for personal gain is acceptable in the society of that time (and maybe even in some Muslim societies today). More importantly I also accept that there is no evidence at all that he ever mistreated Aisha and by all accounts (hers and other eye witnesses) it was a very loving marriage.
I take great pains to refer to Muslims thinking and not Islamic precepts. I believe that the challenge for Muslims today is to make Islam relevant to today, instead of trying to recreate a 7th century Arabic modes of practices down to laws instituted for the social values and dress codes of those days. For that Muslims need to break away from the literalist interpretation of the Quran and see the truth contained in it behind words in the Quran. For God does not look at actions but what is in the heart. It is not what you do that saves you but why you do it; it is not scrupulously following all the actions dictated in the Quran but doing them all for the right reasons - because you love and care for your fellow men. Only then can Muslims become truly Islamic.
