Where do you draw the line between conservative, right-wing, extremist right-wing and fascist? This separation is completely subjective. I personally would consider them quite close to right-extremism but I am what they would call a "Linksversiffter Gutmensch" (which could be roughly translated as "Leftist-scum Goody Two-Shoes"), so do not take my word for granted.
But just this month the party had a national convention where they presented their new program. The newspaper "Zeit" wrote an article about it. I am just going to translate the section-headers:
- More citizens referendums
- More surveillance
- Harder prison punishments
- Dissolve the European Union
- Smaller state
- Reduce taxes (mostly for the upper class)
- Reduce social welfare
- Women back into the household
- No women quotas
- Make divorces more difficult
- Make abortions more difficult
- Close borders to refugees
- Limit religious expression of Muslims
- No actions against climate change
- More nuclear energy
- Increase the Army
- More government-controlled media
- Alcoholics, Drug-addicts and people suffering from mental illness into prisons instead of therapies.
- More private weapons
- Legalize drugs
- Increase privacy protection
- No speed limits on highways
Zeit is, like all mainstream media in Germany, frequently denounced by the AfD as "Lügenpresse" ("lying-press"), so don't take their word for it. If you want to form your own opinion, study the primary sources.
