I think part of it is getting used to the situation. There is an ongoing battle between the military and armed-islamic groups. It is not a heavy conflict but this (https://thedefensepost.com/2019/04/27/tunisia-soldier-killed...) happened very recently and it is not a unique case.
There has also been several civilians either kidnapped or killed by armed terrorists. It has become common now and people stopped talking about it.
Also Tunisia has got a significant forgotten population. Think people with no access to water, electricity, roads, education... most Tunisians you'll see in the nicer neighborhoods do not relate to those and probably don't remember them except for some brief Facebook posts.
Tunisia rural population is around 30%. That's a third of the population. Compare that to 10% in Venezuela.
To answer your questions:
1- It is more likely we don't reach a consensus on how bad Tunisia is. You should take into account that probably neither of us went to Venezuela in the first place.
As an outsider I'd be interested if the two of you can reach consensus by precision and what the resulting agreement would be.
Perhaps these parts of Tunisia can be specified?
