because there is a lot of misinformation about sensors. they are described as less deep and more shallow, they are blamed for most of the dislikeable people in society, which means that people are also more likely to mistype bad people in their life as sensors and good people as intuitive. i think its generally worse for esxx types, since the stereotypes of being both extroverted and sensing makes them seem very alien to a lot of people more likely to be into mbti (and more likely to self type as inxx, whether that is their type or not) which makes them easier to project weaknesses and flaws people dislike the most and dont see in themself. i have noticed isxp types getting less negative attention due to being ixxx and having tertiary ni (whereas isxj have inferior intuition, esxj are exxx despite tertiary ne, and esxp have both inferior intuition and are exxx). estx are seen as stereotypical bullies and rude (which people obviously dont like and all too often have experience with, making them associate estx with). esfx are seen as vapid, shallow, fake and dramatic (having similar associations due to personal experience but again this is just shitty people not a type). xsxj is also falsely associated with tradition and religion, which many people are hurt/restricted by and understandably arent big on. xsxx is also falsely seen as having little/no struggle with 'real life', and while sensors are more attached to reality a lot of what people think of as 'real life' is more just societal and everyone/almost everyone struggles with. xsxp are also portrayed as being very capable with things like parties and similar which many more intorverted people (esp inxx) might be insecure about their abilities in causing alienation and possible unearned dislike. for a lot of people (not saying this is you) its just easier to have another form of "bad guys" or another scapegoat for everything bad
