It is not the best source but the Wikipedia summary of the grounds on which bail is given show that Judges have considerable scope to assess the risk in granting bail.
"Any person accused of committing a crime is presumed innocent until proven guilty in a court of law. Therefore a person charged with a crime, should not be denied freedom unless there is a good reason.
The main reasons for refusing bail are that the defendant is accused of an imprisonable offence and there are substantial grounds for believing that the defendant would:
1.Abscond
2.Commit further offences whilst on bail
3.Interfere with witnesses[5]
The court should take into account the:
1.Nature and seriousness of the offence or default (and the probable method of dealing with the defendant for it)
2.Character, antecedents, associations and community ties of the defendant,
3.Defendant's bail record, and
4.Strength of the evidence[5]"
Where evidence is not strong and no previous convictions or charges then it seems reasonable to grant bail to men accused of rape. Where evidence is strong and previous convictions or charges have occured the risk would be far higher and bail would likely not be granted.
Given these criteria, I am therefore unclear what grounds it was granted in this case.
I think it is possible for a fair and reasonable society to be both concerned about men being falsely accused of rape and their lives ruined and at the same time having a duty to protect victims. The job of judges is to use their judgement in witholding or granting bail and hence to express society's dual concerns about treating accused and victims fairly.
It is not a simple black-and-white question about whether men accused of rape should be granted bail or not.
It requires judges to judge.
