How can you hate Macron? He's like crÃ¨me brÃ»lÃ©e - bland, tasteless, inoffensive. Sweet and safe to feed to small children and sick people. The least divisive of all possible dessert-options. Nobody loves it. Nobody even really enjoys it. But you can't hate it because there's nothing there to hate.
If candidate X is supposedly divisive, it means that society is already divided and gave that particular candidate a mainstream platform. Electing candidate Y because he's the least divisive won't make society any more united, it will more likely increase the divisiveness within society, particularly if candidate Y dismisses the concerns of the people who support candidate X. Governments have an obligation to the people they represent and to reconcile different perspectives and bring everyone to the centre.
I think there are many reasons to dislike or distrust Macron, including his failure to deliver as finance minister (he was the architect of the current - and failed - economic plan) and his support for the normalization of terrorism. He's extremely inexperienced in matters of security and he'll lead a country that's currently under state of emergency - the recipe for disaster.
Personally, I wouldn't trust a guy whose party's acronym are his own initials. He screams elitism and hypocrisy.
