Well to be perfectly honest , Jews have lived side by side Muslim governments in past. Their court cases are quite document in Prophet's time cases involving Jews / Muslims etc
It is perhaps the education , criculum in our society that does not covers the various interaction of Muslims with other civilizations and various pacts and agreements of last 1500 years. Our focus is merely on perhaps 50-100 years
And it is quite well documented how they lived in various Islamic civilizations in past.
The modern world views the Jewish dispora from view of last 200-350 years perhaps and more dominantly in last 100 years.
If a peson is attracted to Holy lands , it is not our job to say you can't visit who know he might become a Muslim by visiting some of the sites
- A ban on visitation based on Military Espionage or Damage to civil order is a different matter and each country have their own rules and regulations on that respect
The present Age dislike of Israel is rooted in their extraordinary , aparthied government and way of treating other minorities such as Palestinians which is why they are excluded from invitation. It is a more less their modern time actions which have tainted their over all view in Muslim countries
The person who visited did they break civil law and order ? Perhaps becasue travel ban does exist on certain foreigners. This is noting more then a individual person taking extra ordinary risk to travel to restricted areas and nothing more
It is difficult to really say , if person is visiting due to sincerety and enlightenment or not ...
If None Muslim is interested to learn about Islamic culture or sites , we can't really just deny the person unless there was a valid reason or ill intent
From Muslim's point of view these are places of worship and not really tourist attraction and this there is a general backlash becasue places of worship in Muslim view are not places seen as Tourist attraction.
