Many on the right either deliberately or through ignorance refuse to understand that there are many forms a left-wing state can take. To some anything at all that is further to the left than the "right-of-centre" is just commies. There's no point engaging with these types as their minds are clamped shut.
Norway is of course one of the most socially advanced nations on the Planet. It is also currently regarded as the most democratic country on Earth. Venezuela on the other hand is an economic basket case sliding into authoritarianism. The nations are not readily comparable with extremely different social and political genealogies.
Important point here: There is a significant difference between "social democracy" and "democratic socialism". Changing the order of the words does make a major change in meaning. "Social democracy" is the Scandinavian hybrid of free market capitalism married to a highly developed cradle-grave social welfare system. "Democratic socialism" on the other hand is an ideology further to the left - a democratically elected socialist polity with much state controlled means of production and centralised infrastructure.
Whereas "Social Democrats" are seen as a liberal left-of-centre form of government (and the predominant form seen in modern Europe), "Democratic socialism" basically occupies ground closer to communism. (of which Venezuela is one of the very few examples).
The terms get mixed up all the time so it can get very confusing.
Norway is the model of social democracy. In fact the country is so well tuned right now that practically any change Norwegians made to their political system would probably lead to a reduction in freedoms.
It's not all just because Norwegians are uber-generous, inclusive and peace loving (although that's usually true). Norway is by luck of demographics and geography an immensely wealthy state. Norwegians are practically tripping over the natural resources the world hungers for. They are able to run almost their entire infrastructure on cheap renewable energy and they have very friendly neighbours who share all their ideals. In many respects they are lucky b@stards for whom in the modern world it is easy to run a utopia.
Venezuela on the other hand hasn't had so easy a time of it lately. Their socialist government was for a time very effective at bettering the lives of their citizens but their over-centralised command economy was unable to deal with the collapse in oil prices upon which their wealth was based. They have 6 times the population of Norway, income sources that are nowhere near as diverse, only a fraction of Norway's wealth and have infrastructure nowhere near as highly developed. Their main problem right now is that their government is headed by a president who is bulldozing the rights of his people in a desperate bid to retain his power. Venezuela may have been democratic socialists but it's hard to call them democratic anything these days. They're now on the borderline of dictatorship
Incidentally Norway's democratic freedom rating is: (out of 10) 9.9. Venezuela's is 3.9 and falling.
As you say, blaming socialism for their current problems is not really looking at the wider picture of ill fortunes affecting the nation. But that doesn't stop those with a political agenda claiming that Venezuela is what any nation who adopts socialist principles will turn into despite the clear evidence that this is arrant nonsense.
