Answer:
A similarity between the two is that ideologies can cause partisanships. A different between the two is that ideologies is just a set of beliefs, while partisanship is an act of prejudice BECAUSE of those set of beliefs or ideologies.
Step-by-step explanation:
Ideology is basically a system of ideas or beliefs in a certain group of people perhaps religion, country, culture. Ideology could just be between one person; one person can have a personal set of ideas or theories or beliefs about different topics.
Partisanship is basically prejudice due to another person's own bias. Partisanship is basically actions or hateful actions due to someone's personal system of beliefs or ideologies.
Knowing the definitions of the two now you see that Ideology and Partisanship go hand in hand. Some similarities may be that because of a person's ideologies it may cause prejudice to a certain group of people. For example, if you say hateful things or commit hateful acts because you believe that a certain group of people are bad and that the world will be better without them, that's a partisanship being biased and for a particular cause. Another similarity is that ideologies can cause partisanships. Now for differences between the two is that ideologies are just a set of beliefs, while partisanship is an act of prejudice BECAUSE of those set of beliefs or ideologies. Ideologies are ideas of the mind while partisanship are actions because of those ideas in the mind.
Hope this helps.
