I have seen the issue come up time and again since Pole got more into the mainstream fitness industry.
"Someone thinks pole dancing is shameful!"
Whether it be a city who has to decide whether to "allow" a pole studio to set up shop, to certain people's brothers making lewd and unkind comments, all the way to "How does your husband let you do that?" and even being shunned by one's friend group, or family, because of a hobby.
I've even heard from a UK university that "women are being tricked into thinking that pole dancing is empowering, when it's really not."
All somewhat insulting, all frustrating, and all things I could get rant-y and political about (accepting women as actual business people, proper boundaries between family and friends about certain comments, assuming someone is "owned" by their husband, and all-around trying to keep women down, and desperately trying to keep them away from taking up space, being sexual, and being empowered), I'll try to refrain.
In reality, we have to accept something: Pole dancing, in the western society, is strongly linked to stripping. This is where we first learned of dancing upon a pole, this is what we associate naturally with pole dancing, unless we've been conditioned not to for a very long time. Even I, who does not go to strip clubs and only has connection to poles through fitness, still think of it as "a stripping thing."
And, we continue to enjoy the sexual nature of it. In many ways, increasing your "flow" and getting in touch with your sexy side is taking advantage of that western-world history of strip tease and womanly power on stage.
In my opinion, this is nothing bad. We're using this sexual energy, this internal energy, in a way that empowers us, that encourages us to "take up space" and be ourselves, to live and breathe something that all people know to be powerful, engaging and brilliant.
Otherwise, in the real world, "dealing with it" is something very personal, and depends on you, and your relationship to the person who is doing the shaming- be it overt or covert.
Your mom made a comment about taking the pole down because of company coming over, so, there are some questions to ask yourself: How comfortable are you being upfront about the issue, without being insulting, attacking, or confrontational? How aware do you feel your mom is, in order to conduct such a conversation in a way that will not result in either of you coming away feeling unhappy, insulted, or attacked? How much energy are you willing to invest into the conversation (as in, is it worth having, considering the expended emotional and mental energy)?
I will say this: The issue could have nothing to do with you, and everything to do with her. Many people these days worry about what other people think. She could be thinking more about the judgements they place upon HER about how she's raising you, and whether she is encouraging you toward values that are against the values that she, and these guests, hold dear.
And, it might be entirely as AllysonKendal said: It may just be a little bit in the way, or distracting to some guests.
